Ian Bremmer's Quick Take:

Now that the war in Afghanistan is just about concluded, less than 24 hours before all of the remaining American troops wrap up their mission in Hamid Karzai International Airport in Kabul, after over 100,000, mostly Afghan civilians, as well as American and coalition partners evacuated from the country. One thing to point to is just how much the United States and the American people have changed in interests, in what presence, what the role, what the mission of the United States globally is and should be.

As everyone now is very keenly aware, this war became very, very unpopular among Democrats, among Republicans. If there was anything you could find people agreeing on in foreign policy, it's, "We're angry at China, we want to end the wars. The war in Iraq, the war in Afghanistan, why are we doing all this stuff?" In other words, the idea that the United States is the global policeman. A role that the Americans had accepted to a great degree during the cold war, accepted to a significant degree after 9/11, really doesn't accept any more. And so, I think one of the reasons why people give such a hard time to this America is back idea of Joe Biden is that, there are many things about America's history that a lot of Americans increasingly aren't up for. The idea of being the global policeman. The idea of being the architect of global trade. The idea of being the promoter of common values, of an open society and rule of law and human rights.
