"At some point, after all, the calculus of conformism will begin to shift. It will become awkward and uncomfortable to continue supporting “Trump First,” especially as Americans suffer from the worst recession in living memory and die from the coronavirus in numbers higher than in much of the rest of the world.
Or perhaps the only antidote is time. In due course, historians will write the story of our era and draw lessons from it, just as we write the history of the 1930s, or of the 1940s. The Miłoszes and the Hoffmanns of the future will make their judgments with the clarity of hindsight. They will see, more clearly than we can, the path that led the U.S. into a historic loss of international influence, into economic catastrophe, into political chaos of a kind we haven’t experienced since the years leading up to the Civil War.

Late in his life—he lived to be 93—he summed up the philosophy that had guided him through all of these tumultuous political changes. It was not idealism that drove him, or big ideas, he said. It was this: Warto być przyzwoitym—“Just try to be decent.” Whether you were decent—that’s what will be remembered."
