Trump đang biến nước Mỹ thành một bãi rác.

In this sense, nationalism is not patriotism, which is the desire to work on behalf of your fellow citizens, to defend common values, to build something positive. Nationalism is not community spirit either, which seeks to pull people together. Nationalism has nothing to do with democratic values: Authoritarians can be nationalists; indeed, most are. Nationalism has nothing to do with the rule of law, justice, or opportunity. At its core, nationalism is rather a competition, an ugly and negative competition. There’s a reason nationalists build walls, denigrate foreigners, and denounce immigrants: Because our people are better than those people. There’s a reason nationalism has so often become violent in the past. For if we—our nation—are better, then what right do others have to live beside us? Or to occupy land that we covet? Or even, maybe, to live at all?

Sure, people pretend otherwise. We’re just defending our right to be unique! We just want everyone to stay in their own country! We just like our own culture! But that’s not really what nationalists think, and everyone knows it. They can nod and wink at equality among nations, but really they are motivated by, driven by, addicted to a feeling of superiority. Our county is better than your country. So stay out.

I hear this when Donald Trump uses the slogan “America First”: This is why he needs a physical wall at the Mexican border; this is the source of his dislike for immigrants, for people with unfamiliar surnames or different skin colors. He regards all of them as lesser, inferior people who somehow got inside our borders and made our country worse. He and the claque who support him repeat these things over and over again because this kind of nationalism requires reinforcement. It thrives on stories and pictures, songs and chants, repetition. It needs a constant stream of evidence, constant proof of superiority.

But what happens when the stream stops? What happens when the stories and pictures no longer match? More to the point, what will Trump do, what will his followers and admirers do, when their understanding of the world is flipped on its head? What will happen when they realize that other countries are building walls between them and the United States?

Here it’s worth pointing out a genuine oddity: The world in the age of the coronavirus should be a nationalist’s paradise. Borders have slammed shut. Countries have fallen back on their own resources. Multiple international institutions have failed, in major and minor ways, starting with the World Health Organization, the one group that was explicitly created for this moment, and continuing on to the G-7, whose members can’t even manage to meet for coffee.

And yet, has there ever been a more global moment? Everyone in the world is living in the same isolation, with the same fears. Everyone is working on the same vaccines, exchanging notes about the same cures. Everyone is trying to solve the same medical, psychological, and economic problems. Everyone is dealing with a virus that seems completely uninterested in the national origins of the people it infects. More to the point, everyone can look at everyone else’s country, read its media and social media, see how its institutions are coping with the crisis. We can’t leave our houses, but we can meet in cyberspace, where we can keep talking.

While we are there, we can see how other countries are dealing with the pandemic. Some are doing well, especially those that have decent bureaucrats, respect for science, and high levels of trust: South Korea and Taiwan, Germany and Slovakia, much of Scandinavia, New Zealand. Some countries are not doing well, especially those run by divisive populists on both the left and the right: Russia, Brazil, Mexico, and, of course, the United States. But even within this latter group, we stand out. Out of all these countries—out of all the countries in the world—the U.S. has the largest number of cases and the highest death toll. The U.S. isn’t merely suffering; the U.S. is suffering more than anybody else.
