Five years since Paris Accord: Are we any better?

Global warming and rise in sea level

Today marks the fifth anniversary of the Paris Accord hammered out by more than 190 countries at the 21st Conference of Parties (COP21). The core objective of the accord is to save humanity from the existential threat posed by climate change. To that end, the participating nations agreed to keep the increase in the average global temperature to within 2 degrees Celsius while endeavouring to limit it to 1.5 degrees by the year 2100. Besides pledging to temper the rise in temperature, they agreed to restructure the global economy, phase out fossil fuels over the coming decades, switch to renewable sources of energy, embrace clean technology, and most importantly, reduce greenhouse gas emissions to zero by 2050.

The Accord gives every country the ability to set its own goals to confront the climate crisis, in line with their specific situation. Moreover, instead of demanding expeditious and deep cuts in fossil fuel usage, it allows parties to peak greenhouse gas emissions “as soon as possible” followed by a gradual decrease in order to reach the zero emissions goal. It is patently evident that such a vague timetable fits the interests of the major polluters, including the United States, China and India. Nevertheless, beginning this year, each nation is required to reassess its own reduction plans once every five years. However, there is no consequence or penalty if a country fails to reassess or falls short of the pledged reductions.

The Accord also requires nations to address “loss and damage” caused by climate impacts. Since the wealthy, industrialised nations are largely responsible for the backlog of climate changing emissions lingering in the atmosphere, they should compensate poorer nations for unavoidable loss and damage. But even after COP25 held in Madrid last year (2019), wealthy nations are playing Jekyll and Hyde roles—promising to cover losses while dragging their feet on providing new finance.

We are now a full five years into the Paris Accord which, according to the former US President Barack Obama, is supposed to make the “world safer and more secure, more prosperous and more free.” Are we really on course to transform our planet into one as envisioned by Obama? Are we winning the race against climate change? Did we succeed in slowing down the damage resulting from climate change? By all accounts, the Accord did not make an iota of difference in decelerating the progression of our planet, and subsequently our civilisation, toward climatic meltdown. On the contrary, climate change and its deleterious effects are accelerating, with climate-related catastrophes piling up, year after year.

Our planet is now almost at the breaking point. The environmental changes sweeping across the world are occurring at a much quicker pace than five years ago. As the Earth warms, we are witnessing more cataclysmic wildfires turning forests into carbon dioxide emitters, not to mention calamitous floods inundating nearly half of landmasses in countries like Bangladesh, Maldives, Thailand and so forth. Persistent droughts, fierce storms and an increase in extreme weather phenomena—derecho, microburst, bombogenesis, Frankenstorm and many more—are on the rise. The fingerprints of climate change since 2015 can also be seen in the exacerbation of internal and international migration patterns of climate refugees.

Scorching heat waves, of all places, in the Arctic region, are now more frequent and long-lasting. It is quite likely that 2020 will be among the hottest years ever, even with the cooling effect of this year’s La Niña. Seas are warming and rising faster, putting more coastal cities at risk of going under acidic water. Warmer waters are wreaking havoc on marine organisms forcing them to migrate away from their familiar habitats. Glaciers are melting at an alarming rate, thus disrupting availability of freshwater.

Climate-induced mayhem is taking a heavy toll on the Arctic region. The amount of Arctic sea ice whose whiteness normally acts as a natural reflector of heat back out of the atmosphere is dwindling so rapidly that the region may soon become ice-free. Loss of ice is also changing the Arctic terrain—making it greener and prettier, but at the expense of releasing copious amounts of carbon dioxide and methane trapped in the frozen soil, which in turn is making global warming even worse. Additionally, scientists have found evidence that frozen methane deposits in the Arctic Ocean, worrisomely called the “sleeping giant of the carbon cycle,” are escaping into the atmosphere. In fact, northern landscapes are undergoing massive change, with potential ramifications not just for the Arctic itself, but the world as a whole.

Permafrost in cold climate countries is thawing at breakneck speed, releasing, just like Arctic ice, large amounts of long-stored carbon dioxide and methane. In addition, viruses and bacteria that had been buried under the permafrost for thousands of years are being released into the environment, posing health risks to humans and other forms of life. Also, deforestation of the Amazon rainforest in Brazil, a vital carbon sink that retards the momentum of global warming, has surged to its highest level since 2008.

As for peaking of emissions, there is a cavernous gap between the sharp cuts in emissions required to meet the goals of the Paris Accord and current projections. In a recent report, World Meteorological Organization (WMO), a specialised agency of the United Nations, states, “There is no sign of slowdown, let alone a decline, in greenhouse gases concentration in the atmosphere despite all the commitments under the Paris agreement.” Rather, emissions from just about every country are still on the rise, thereby making it difficult to close the gap so as to achieve zero emissions by 2050.

The report further notes that even the coronavirus-related drop in emissions failed to make much of a dent in the amount of heat-trapping greenhouse gases accumulating in the atmosphere. Consequently, WMO warns that the world risks becoming an “uninhabitable hell” for millions unless we drastically cut emissions—by at least 7.2 percent every 10 years if we want to keep the rise in temperature to 1.5 degree Celsius. Otherwise, we will soon be north of 3 degrees Celsius.

The warning from WMO is corroborated by a study published last month in the British journal Scientific Reports, in which the authors assert that we have already passed the “point of no return for global warming.” The only way we can stop the warming, the authors say, is by extracting “enormous amounts of carbon dioxide from the atmosphere.”

The Earth’s average temperature has already risen by roughly one degree since the advent of modern record keeping in 1880. The devastation caused by one degree rise clearly indicates that an additional 1.5 – 2 degrees Celsius rise before the end of this century will lock in the changes to the Earth’s climate system that will be beyond our adaptive capacity.

Five years ago, the then UN chief lauded the Paris Accord as a landmark agreement, a potent message from world leaders who had finally decided to take on climate change in earnest. Five years later, in a complete volte-face, the present UN chief, in a speech at Columbia University in New York, issued a searing indictment of our utter disregard for the pledges made in Paris. He said, “The state of the planet is broken. Humanity is waging a suicidal war on nature, facing new heights of global heating, new lows of ecological degradation….”

So much for the Paris Accord! No wonder environmentalists believe that the Accord is meaningless, and with good reason. Indeed, the toothless, nonbinding, non-enforceable accord is an oversold empty promise—a gentleman’s handshake applauding the imposition of a global climate regime on humankind that is harming the planet in the name of saving it.

Finally, world leaders should realise that fixing the climate is not about making pretty promises at grandiose conferences held in glamorous cities. And if we rely on grandstanding and farcical Accords that give us false hopes, we will lose the race to keep our planet cool and habitable.

An Open Letter to Humans from COVID-19

The COVID-19, a strain of coronavirus, sends an open letter to Humans on the occasion of Christmas 2020:


Dear Humans,

I am totally astounded and flabbergasted by the audacity you have displayed so far to my strength and ferocity. I may be small, a very small strain of coronavirus, but I am not weak. About a year and half ago, I evolved in your planet in the most populous nation on Earth. I thought I would have a fun time jumping from one to the other of 1200 million of your species. But Chinese government reacted very promptly, to my utter disgust, forcing me to stay within the confines of only 10 million or so Chinese. I will never forget or forgive the Chinese.

You know that I am a virus and hence I cannot live on my own. I need a body, preferably, a sick human body – a body with underlying problems like respiratory illness, diabetes, weak hearts having transplanted or bypassed, kidney problem, dementia and a lot of other problems, as my host. I do not want to go to anybody who is not prepared to be my host. After all, who does not like an easy prey, an easy meal? I hate going to a strong healthy body and fight it out with his or her body protection system.

You call your body protection or defence system an immune system. There is nothing immune from my attack. I am smaller than the smallest of a bacterium. You cannot normally see me or detect me unless you take me to an electron microscope. Even then, you have to be very careful detecting and photographing me. You take the shot from a wrong angle and you miss the point.

As I said, I need a host. I am not even alive on my own; unless I find a live cell in a live body like yours as my host within few hours, I would die. Once I get a host, I seek out the weak organ or tissue where I will have an easy task. First, I go to an organ of your body as an innocent bystander, observe how strong your organ is and how efficiently it is functioning. If the organ I am in is very efficient, then I tend to slip away to another organ. After all, I don’t want to sacrifice my life fighting a losing battle with a strong organ, whereas I could have a very comfortable life in another organ where I can flourish, multiply and even take over the whole organ!

When I multiply in an organ or capture the whole organ, I do not want to rest on my laurel. I want to go from your body to another body and keep capturing bodies. I use your cells as my hosts, your body as my survival machine. Before I make you inert (you know what I mean), I want to send some of us to some other human beings. I make you sneeze, make you cough, touch mucous membrane with your hands and pass it on to another person. I need your helping hand, literally. In fact, the more the merrier.

I hear that you have invented a vaccine against me, you want to kill me. It is then going to be an all-out war with me. I have lots of tricks up my sleeve – actually, up my spike to be precise. You think you can catch me by my spike, sort of catch a bull by the horn? No way. I will change my morphology such that as soon as you plan to bolt on to my structure, I will metamorphose to something else. Actually, I do not like the word metamorphose, as if I am doing a literary piece of work, I call it mutate. I mutate, I make your body cells mutate until those cells fail to function.

Mutation is the word I like most. As soon as you make something to catch me, you would find me that I have changed, I have mutated. It’s a cat and mouse game. And then you start the whole process all over again, back to square one. It goes on and on.

In all of this battle of wits, you forgot that I and my cousin called bacterium were the seed corns from which you were made. From the single cell bacteria to multicell bacteria and then to complex bacteria with RNA, DNA and mitochondria, that is how you came into being. Don’t forget all that of your past.

During the long evolutionary period of nearly four billion years, my cousin bacterium had done tremendous amount of work for you. You, all types of animals from antelopes to zebras, plants, fungi and algae were all made from innocent bacteria. My role was to terminate any unworthy species. Your fellow man, a very clever guy called Charles Darwin, very succinctly said, “struggle for existence and survival of the fittest.” I make that struggle as hard as possible and so don’t underestimate me.

May I remind you that during the last 450 million years when conditions on Earth were getting progressively favourable to you, as many as five times, 70 to 75% of all species of all living animals and plants had been wiped out. In addition, about 250 million years ago, nearly 99% of all life forms on Earth were obliterated. It was nearly going to start from a blank slate again. About 65 million years ago, dinosaurs were wiped out completely and that created conditions for life forms for you to evolve.

Life on Earth is a perpetual struggle. I quote again, Charles Darwin’s dictum, “struggle for existence and survival of the fittest” and this struggle and survival come from evolutionary process. If you, the human beings, think that you are clever enough and smart enough to override the evolutionary process, then you better think again.

One last point I would raise is that do not, not even in your dream, think that you are going to live on this Earth for ever. Since the dawn of life (any life) about 400 million years ago, 99% of all life forms have gone extinct. You came to Earth evolving from chimpanzee about 4 million years ago, less than 1.8 million years ago as Homo erectus or only about 200,000 years ago as Homo sapiens.  A species on Earth lives, on the average, 4 million years and so your time is very much nearer the end. You had been destroying the fabric of Earth, massacring the environment, causing extinction to many species. Probably you had been creating conditions for your own demise. SO BE WARNED!

Black Holes and the 2020 Nobel Prize in Physics

2020 Physics Nobel Prize winners

Three scientists have been awarded the 2020 Nobel Prize in Physics. They are the British mathematical physicist Roger Penrose, German astrophysicist Reinhard Genzel, and American astronomer Andrea Ghez.

Penrose, a professor at Oxford University, is recognised for his research on black holes carried out in the 1960s. According to the Royal Swedish Academy of Sciences, Penrose has been honoured “for the discovery that black hole formation is a robust prediction of [Albert Einstein’s] general theory of relativity.” Professors Genzel of Max Planck Institute and Ghez of the University of California in Los Angeles were awarded the prize “for the discovery of a supermassive compact object” in a region called Sagittarius A*, located at the centre of our galaxy, The Milky Way.

The criteria for awarding Nobel Prize in Physics are defined in specific terms. Alfred Nobel’s Will stipulates that the prize should be awarded “to the person who made the most important discovery or invention in the field of physics.” The crucial words in the Will are “discovery” and “invention.” It is arguable whether developing a theory can be considered a discovery per se, but it is certainly not an invention in the sense that we normally associate an invention with. That is why the prize is seldom given to theoretical physicists, unless their theory is testable or verifiable.

When theorists won the prize by themselves, for example John Bardeen, Leon Cooper and Robert Schrieffer for their theory of superconductivity, it was for a major theoretical formulation of an existing phenomenon, and thus can be considered as part of the “discovery” of that phenomenon. And theoretical physicists Peter Higgs and François Englert were awarded the Nobel Prize after the particle—Higgs Boson—predicted by their theory to complement the Standard Model of the Universe was experimentally detected.

While the awards to Genzel and Ghez are incontrovertible because they fit Nobel’s criteria quite nicely, Penrose is a rather unusual choice in that his award is not for a discovery. It is for using ingenious mathematical methods to reveal the implications of Einstein’s tour de force—the intimidatingly difficult-to-comprehend Theory of General Relativity.

However, long before Penrose’s prize-winning work on black holes, German physicist Karl Schwarzschild provided the proof of their existence just less than two months after Einstein published the general relativity equations in 1915. By solving the equations exactly, he identified a radius, known as the Schwarzschild radius that defines the horizon or boundary of a voracious gravitational sinkhole—a single point of zero volume and infinite density.

If a massive object could be compressed to fit within the Schwarzschild radius, which is three kilometres per solar mass, no known force could stop it from collapsing into the sinkhole. Today, we call this sinkhole a black hole. His work formed the basis for later studies of black holes, showing that the concentration of matter in a black hole is so great that no light could escape its staggering gravitational pulls, but rather follow a trajectory curving back towards the black hole, thereby making it unobservable.

Lest we forget, Einstein did not win the Nobel Prize for his revolutionary work on general relativity or special relativity. The Nobel Committee decided against them on grounds that the relativity theories were abstract and unproven, although observational proof of general relativity was provided in 1919 by the Cambridge astrophysicist Arthur Eddington. He famously measured the deflection of starlight passing near the Sun during a total solar eclipse. The deflection, known as gravitational lensing, resulted from warping of space, as predicted by general relativity. Instead, Einstein received the deferred 1921 prize in 1922 for his 1905 quantum interpretation of the photoelectric effect because it can be attributed to the discovery of the effect—emission of electrons from metal surfaces under certain illuminations—by the German physicist Heinrich Rudolph Hertz in 1887.

Despite his fame and impact on theoretical physics, Nobel Prize eluded the brilliant physicist, mathematician and cosmologist Stephen Hawking, even though there is a general consensus that he has done more than anyone else since Einstein to deepen our knowledge about the cosmos. As noted by Penrose, a Nobel Prize for Hawking would have been “well-deserved” yet was possibly held back by the committee’s desire to honour observable, rather than theoretical scientific studies that are difficult, or almost impossible, to verify experimentally. Penrose’s work, albeit monumental and worthy of the Nobel Prize, cannot also be experimentally verified because of the very nature of the topics. So why relax requirements for work which are mostly theorems, some hypothesised in collaboration with Hawking?

Penrose is not the first scientist to predict the existence of black holes. The idea of black holes dates back even before Schwarzschild, to 1783, when an English cleric and amateur scientist named John Michell and more than a decade later French mathematician Pierre-Simon Laplace used a thought experiment to explain that light would not leave the surface of a very massive star if the gravitation was sufficiently large. Michell called them “dark stars.”

In 1930, during a long voyage to London, 19-year-old Indian astrophysicist Subrahmanyan Chandrasekhar showed via calculations that when a massive star runs out of fuel, it would blow itself apart in a spectacularly violent explosion into a black hole. He received the Nobel Prize in 1983, not for his work on black holes, but for “studies of the physical processes of importance to the structure and evolution of the stars.”

For decades, the concept of black holes was no more than a mathematical aberration. They are well-nigh impossible to detect because light, one of our cosmic messengers, cannot escape from black holes. Hence, there is a total information blackout. How do we then infer about their existence? As the physics of black holes developed through the years, physicists realised that indirect routes were available. Consequently, our current understanding of black holes is built on inference drawn from data collected by X-ray, optical and radio telescopes.

Indeed, their existence was eventually confirmed in 1971 when astronomers detected a hint of radio wave emissions coming from an object in the constellation Cygnus. The emissions were later interpreted as the fingerprint of the black hole Cygnus X-1. Since then, numerous black holes, including supermassive ones, have been detected in our galaxy and elsewhere in the Universe.

America at the cliff edge

Why the fate of the American Republic – and the world – could depend on what happens on November 3, 2020.

The survival of the American Republic is at cliff edge now, given the perspective of 244 years of American history. There was the close election of 1800 between Aaron Burr—an unprincipled fellow with dictatorial impulses who was in many ways the Donald Trump of his day—and Thomas Jefferson. The 1860 contest in which Abraham Lincoln faced off against Stephen Douglas, with the Civil War looming. Or the 1932 election during the Great Depression, the stakes of which were so consequential that when Franklin D. Roosevelt (FDR) was warned he might be known as the worst president in U.S. history, if his recovery program failed, FDR reportedly replied, “If it fails, I’ll be the last one.”

An extraordinary consensus exists among historians, political scientists, diplomats, national security officials, and other experts that the stakes of the U.S. presidential election between President Donald Trump and Democratic candidate Joe Biden this November rise to these portentous historical standards. Indeed, the stakes may go well beyond that, considering the central place the United States holds today in the global system—in a way it did not as a much younger nation in 1800, 1860, or even 1932.

Some suggest that Trump and the malign forces he has summoned up have already done so much damage to the institutions of U.S. democracy—especially his failure to contain the COVID-19 pandemic and his open encouragement of racial violence and national division—that his re-election in November could damage forever the 244-year-old American experiment of a republic of laws. After a first term in which Trump has openly defied Congress and the courts, twisted foreign policy to serve his political interests, dismissed electoral norms, and turned a terrified Republican Party into his poodle, his return to power would, in effect, legitimize the gutting of the institutions of law and what remains of the founders’ checks and balances. Re-election would vindicate his view that as president he can, as Trump himself said, “do whatever I want.” It would all but destroy the American conceit that the United States is a different kind of democracy, leaving the country as just another abject discard on the ash heap of failed republics going back to ancient Rome and Greece.

The concern is shared by many Republicans—former senior officials who worked for previous Republican administrations stretching back to Ronald Reagan, including several who worked for Trump himself. Some have openly warned that a second Trump term represents an existential threat to American democracy.

“This is a kind of fulcrum moment,” said Edward J. Watts, a University of California, San Diego historian and the author of Mortal Republic: How Rome Fell into Tyranny. “If Trump is re-elected, then I think the norms and restraints of American democracy disappear completely,” in ways that echo what went awry in past republics. Even if Biden wins, Watts added, U.S. recovery will be a long time coming.

“There’s no question in my mind that it’s the most important election in American history. The stakes are just enormous,” said Charles Kupchan, a Georgetown University political scientist, former diplomat, and the author of Isolationism: A History of America’s Efforts to Shield Itself From the World. “One term is bad enough, but if Trump is re-elected, Americans and people around the world would no longer be able to say the American electorate made a mistake. Instead it would be an affirmation this is the direction Americans want to go.”

Kupchan said the reason this contest is more consequential than those critical elections in 1800 and 1860 is that “the United States was not the most powerful country in the world during those times.

“Basically, we stayed out of other people’s hair then. That’s not the case today, when you have a country this big that has so profoundly lost its way. We are entering an unforgiving period in history. The balance of power is changing. During the era of post-Cold War unipolarity, the system was more forgiving. Even during the Cold War, when the U.S. made a mistake here and there, like Vietnam, it didn’t knock the world off kilter. But at a moment when the West has lost its material preponderance [to China and Asia] at the same time as it’s begun to stumble politically, that’s a double whammy of historic proportions.”

Indeed, because the United States occupies such a central place in stabilizing the global system, the election of 2020 could be compared to other important global realignments that transformed the fates of previous great powers, empires, and diplomatic constructs of international stability.

“Internationally, it is a world-historical moment—America’s role in the world, and the organization of the global system, is also on the ballot,” said John Ikenberry of Princeton University, the author of A World Safe for Democracy, a book chronicling two centuries of liberal internationalism. “If Trump wins, the whole post war liberal order continues to unravel, and democratic and other allies of the U.S., who are hedging and hoping that the U.S. will return to playing a ‘system role,’ will start making other plans.”

Harvard University’s Joseph Nye, also one of the leading political scientists and diplomats of his day, agrees. In an interview, Nye quoted a leading diplomat from an allied European nation as telling him recently: “We can hold our breath for four years. Eight years is too much.”

According to former U.S. Ambassador to NATO, Ivo Daalder, if Trump is re-elected or manages to seize power by contesting the election—he is already accusing Democrats of fraud and in late September refused to commit to a peaceful transition of power—it would be tantamount to a formal divorce from Europe and the West. It would mean that “the way Americans view themselves has become completely alien to what used to be the European view of America.” For four years, Trump has derided long-standing European allies and recently, in a fit of pique, announced he was withdrawing thousands of U.S. troops from Germany. The U.S. government’s inept response to the COVID-19 pandemic has only solidified this sense of alienation and frank disgust, Daalder said.

(In August, a special report from FP Analytics ranked the United States 31st out of 36 countries for its response to the coronavirus pandemic, coming in below Brazil, Ethiopia, India, and Russia. The report found that the United States ranked so poorly because of the Federal Government’s inability to mount an appropriate scientific response; inadequate emergency health care spending; insufficient testing and hospital beds; and limited debt relief.)

So abysmal has been the country’s performance under Trump that the Irish Times columnist Fintan O’Toole wrote in April that for the first time the United States is provoking pity from the rest of the world, which sent disaster relief to Washington rather than the other way around.

“What happened during COVID-19 represents the pinnacle to this disgust,” Daalder said. “The COVID response shows so clearly the deep problems with the American system—with our health care infrastructure, the income inequality and racial problems that persist. America has become something to be looked down at.”

The best hope, many pundits and scholars say, is that Trump is soundly defeated in November and accepts that outcome, even though he has suggested he won’t. Eventually he comes to be seen by the world—and by history—as a strange aberration, a one-of-a-kind oddity whose jingoism, narcissism, and incompetence are unlikely to come along again, whether in a Republican or Democratic president. The United States then re-joins the global system—with its usual blend of nativist reluctance and exceptional arrogance, yes, but on a more moderate (or, to be precise, adult) level than during the Trump era.

Under this scenario, a newly inaugurated President Biden, who is a deeply experienced internationalist committed to U.S. alliances, and his multicultural vice president, Kamala Harris, act swiftly to restore U.S. prestige by reversing Trump’s worst failures on COVID-19, political polarization, the economy, global stability, and climate change, as Biden has promised to do. Pointing out that Trump has failed to replace the many international agreements he has torn up, Biden would immediately rejoin and work to shore up the Iran nuclear deal and the Paris agreement on climate change, which he helped champion as Barack Obama’s vice president (and which the United States is scheduled to complete its withdrawal from on Nov. 4, one day after the election). Going by his campaign promises, he will try to revive the Intermediate-range Nuclear Forces (INF) Treaty that Trump has discarded and begin talks to extend the Obama-era New START nuclear reduction pact (which would expire only a few weeks into his term, though even now Trump is seeking to blow it up).

Biden would also likely seek to restore something like the Trans-Pacific Partnership (TPP), the most comprehensive trade deal in history (which has been kept breathing in reduced form by Japan, the United States’ closest ally in Asia, since Trump pulled out of that accord as well). Because the TPP was designed to exclude and pressure Beijing into accepting fair-and-open trade norms, Biden could thereby do far more than Trump has done to confront a rising China and continue to co-opt it into the global system. Meanwhile a paralyzed and polarized Congress—so traumatized by Trumpian divisions, investigations, and impeachment for the past four years—starts working more effectively again (especially if Democrats win the Senate as well as the House, ending the legislative stalemate).

But even in this scenario it’s hard to imagine that things go back to the way they were pre-Trump. Biden, for example, will find it difficult to simply resurrect the INF Treaty and TPP, in part because he must accommodate the powerful progressive wing in his own party, which rejects untrammelled free trade pacts and over commitment to a U.S. military presence overseas. Biden has already said he would not simply re-join the TPP as it existed, for example, but would seek to renegotiate it to include “strong rules of origin” requiring more manufacturing in the United States and has also said, before entering any new international trade deal, he would focus on a Trump-like $400 billion “Buy America” initiative to boost domestic product. Support for the World Trade Organization, which was initiated by Democrats under President Bill Clinton, is fast waning inside the party as well, amid Trump’s accusations that China has unfairly abused its rules to rob middle-class Americans of their jobs. And Biden, like Trump, has been seeking to pare down the United States’ role overseas for years; even as Obama’s vice president, he argued vociferously against a U.S. buildup in Afghanistan and negotiated an accelerated withdrawal from Iraq.

Indeed, perhaps the greater threat is that the stakes of this election are not quite as momentous as optimists hope—and that Trump, even if he loses power, proves to be less an aberration and more a symptom of a country that is no longer functioning well, whether as a republic or a global stabilizer, and can’t be fully trusted again.

After all, Trump’s neo-isolationism didn’t spring from nowhere; it had a lot of popular support and still does. In his new book, Kupchan argues that America’s embrace of internationalism is more an aberration than the norm in U.S. history—and he says that even for the prospective president Biden and subsequent U.S. leaders, “it’s not going to be back to the old foreign policy. We’re not going back to the institutionalized, treaty-based system that emerged after World War II. The votes in the Senate won’t be there.” To that point, a survey by the Chicago Council on Global Affairs released in September shows an unprecedented breakdown in the old consensus in support of Washington’s role, demonstrating the “Trumpification” of the Republican Party, in Daalder’s words.

Perhaps the greatest fear among U.S. allies is that the American republic may simply be caught up in an inevitable cycle of history by which great powers grow complacent and decadent and eventually collapse or wither away. Prominent realist thinkers such as John Mearsheimer have long argued that American-style liberal internationalism contains the seeds of its own destruction – excessive ambition and overreach. “Liberalism has an activist mentality woven into its core,” Mearsheimer has written. “The belief that all humans have a set of inalienable rights, that protecting these rights should override other [domestic] concerns, creates a powerful incentive for liberal states to intervene” abroad.

In recent decades, both Republican and Democratic presidents gave in to this impulse to differing degrees—from Vietnam to Bosnia to Iraq. And in 2016, Trump realized, as his Democratic challenger Hillary Clinton did not, that many Americans had grown weary of being global caretakers when so much was going awry at home, especially the decimation of the middle class under the aegis of rapid globalization. Biden is unlikely to make the same mistake.

Thus, in the perverse way Trump has been channelling the deepest of U.S. traditions and the fears of America’s founders, who were always worried about overreach in foreign conflict and constantly warned against its self-destructive effects, including the rise of demagogues like Trump. Most famously, John Quincy Adams said in 1821 that America must not go “in search of monsters to destroy” abroad; to do so, Adams said, would corrupt the very character of the nation: “The fundamental maxims of her policy would insensibly change from liberty to force.” In the spring of 2016, a senior Trump campaign advisor said that Trump’s first major foreign-policy speech—in which he declared that “the world must know we do not go abroad in search of enemies”—was intended as a conscious echo of Adams and a rebuke to his predecessors and their reckless interventions in Iraq and Libya.

COVID-19 vaccine facing temporary problems

The COVID-19 vaccine development round the world is going ahead in serious earnest. World’s top pharmaceutical companies are going head to head, throwing up their top scientists and technologists as well as investing large amounts of scarce resources, even when their businesses are in doldrums. The governments of various countries are also scrambling to get to the most promising candidate and at the same time hedging their bets simultaneously on a few rival companies.

What is pushing the whole world to this mad rush? The COVID-19, a strain of coronavirus, is the most vicious virus to ravage human species during the last 100 years or so. This virus has claimed more than 27.6 million positively identified infection cases and 898,000 deaths round the world. Needless to say, many more infections and many more deaths had gone unreported and unidentified.

The vaccine against this virus, as in all other viruses, has to go through certain internationally accepted and proven steps to ensure safety and effectiveness to the public. If any short-cut is made or any corners are cut, then the confidence of the public to accept this medicine or any future medicine will be seriously shaken.  

Of the hundreds of potential COVID-19 vaccines now in development round the glove, six are in the final stages of testing. This final stage is known as phase three clinical trial. Each one of these vaccines had gone through phase one and phase two testing before reaching the final phase. Only compromise that was allowed to these vaccines because of the urgency of this medication that phase one and phase two were allowed to be combined and run concurrently. These phases had to show that they are safe (with only short-term side effects, if identified, and no unexpected serious effects) and they elicit an immune response. The third phase is the final stage before approval is offered.

Usually the phase three trial comprises, what is known as case-control study, which is primarily a statistical process. The case group receives the actual vaccine which is being tested and the control group receives placebo i.e. simple saline or vaccine against a different disease. The selection of case-control groups of sample requires careful consideration and vetting. These sample groups should favourably reflect each other in parameters like racial mix, age distribution, gender distribution, economic conditions, patterns of behaviour and social habits.

To demonstrate the efficacy of the vaccine, there must be significantly fewer cases of the target disease in the vaccinated group compared to the control group. Depending on infection rates of the disease, a phase three vaccine trial may involve thousands to even tens of thousands of people. The bigger the sample size, the more reliable would be the output. To be approved, vaccines need to demonstrate that they are safe and effective.

One of these is the vaccine that the University of Oxford is developing – known as Oxford vaccine. This vaccine has passed through phase one and phase two testing with flying colours and now undergoing phase three testing. The purpose of a phase three trial is to assess whether this vaccine-induced immune response is strong enough to actually protect people from COVID-19. The vaccine is designed to provoke a T cell response within 14 days of vaccination – when white blood cells attack cells infected with the SARS-CoV-2 virus – and an antibody response within 28 days – when antibodies are able to neutralise the virus so that it cannot infect cells when initially contracted.

In the Oxford vaccine clinical trial, five countries in five continents have been chosen – India, the UK, South Africa, Brazil and the US. Thus, a wide variety of rich and developing countries in different climatic conditions had been chosen. The vaccine is being evaluated in these regions and hence the result would give a generic output applicable to almost the whole world.

In the first instance, nearly 17,000 people in three countries – the UK, South Africa and Brazil – have received the vaccines, with half being in the control group. These people would then receive booster vaccination between one and three months after the first vaccination. Exactly the same procedure is followed for both case and control groups, so that the volunteers do not know whether they received actual or placebo dose against COVID-19.

The data will be analysed statistically for each country and the results will be scrutinised and assessed by the regulatory bodies. If the results are positive, then regulatory bodies will approve of the vaccine for general use. On the other hand, if the result is marginal then there may be requirements of further improvement in the quality of vaccine or further clinical trial. This will inevitably delay in the use of vaccine by the general public.

AstraZeneca, the firm partnering Oxford to develop the vaccine, is overseeing a scaling up of manufacturing in parallel with clinical testing so that hundreds of millions of doses can be available if the vaccine is shown to be safe and effective. India’s Serum Institute has already started manufacturing the University of Oxford/AstraZeneca vaccine candidate before clinical trials have even been completed. This is to avoid any subsequent delay if the vaccine is approved.

However, a spokesman for AstraZeneca told the Guardian newspaper in the UK that the trial had been stopped to review the “potentially unexplained illness” in one of the participants. The spokesman also stressed that the adverse reaction was only recorded in a single participant and said pausing trials was common during vaccine development.

Notwithstanding the technical issues involved in producing medicines, Donald Trump tarnished the world-wide efforts to produce vaccines with his political agenda of getting re-elected. He declared that the vaccines would be available two days before the US presidential election on 5 November and thereby implicitly and egregiously taking credit for producing COVID-19 cure under his watch!.

However, a group of nine vaccine developers has announced a ‘historic pledge’ to uphold scientific and ethical standards in the search for coronavirus vaccine. The group includes such giant pharmaceutical companies as Pfizer, Merck, AstraZeneca, Johnson & Johnson, BioNTech, GlaxoSmithKline, Moderna and Novavax. By their pledge, they asserted that no matter what the politically motivated pressure may be exerted on them, they will ‘always make the safety and well-being of vaccinated individuals their top priority’. Self-publicised egoistic egregious political leaders will come and go, but the pharmaceutical companies are here to stay to produce and serve the people.
