And it won’t come back even if and when he’s gone.
There are, I suppose, some people who still imagine that if and when Donald Trump leaves office we’ll see a rebirth of civility and cooperation in U.S. politics. They are, of course, hopelessly naïve. America in the 2020s will remain a deeply polarized nation, rife with crazy conspiracy theories and, quite possibly, plagued by right-wing terrorism. But that won’t be Trump’s legacy. The truth is that we were already well down that road before he came along. And on the other side, if the Democrats win big, I expect to see many of Trump’s substantive policies reversed, and then some. Environmental protection and the social safety net will probably end up substantially stronger, taxes on the rich substantially higher, than they were under Barack Obama. Trump’s lasting legacy, I suspect, will come in international affairs. For almost 70 years America played a special role in the world, one that no nation had ever played before. We’ve now lost that role, and I don’t see how we can ever get it back. You see, American dominance represented a new form of superpower hegemony. Our government’s behavior was by no means saintly; we did some terrible things, supporting dictators and undermining democracies from Iran to Chile. And sometimes it seemed as if one of our main goals was to make the world safe for multinational corporations. But we weren’t a crude exploiter, pillaging other countries for our own gain. The Pax Americana arguably dated from the enactment of the Marshall Plan in 1948; that is, from the moment when a conquering nation chose to help its defeated foes rebuild rather than demanding that they pay tribute.
