The argument, for instance, that the situation in Afghanistan was reasonably stable and the war’s death toll negligible before the Trump administration started moving toward withdrawal: In fact, only U.S. casualties were low, while Afghan military and civilian casualties were nearing 15,000 annually, and the Taliban were clearly gaining ground — suggesting that we would have needed periodic surges of U.S. forces, and periodic spikes in U.S. deaths, to prevent a slow-motion version of what’s happened quickly as we’ve left.

Or the argument that an indefinite occupation was morally necessary to nurture the shoots of Afghan liberalism: If after 20 years of effort and $2,000,000,000,000, the theocratic alternative to liberalism actually takes over a country faster than in its initial conquest, that’s a sign that our moral achievements were outweighed by the moral costs of corruption, incompetence and drone campaigns.

Or the argument that a permanent mission in Afghanistan would could come to resemble in some way our long-term presence in Germany or South Korea — a delusional historical analogy before the collapse of the Kabul government and a completely ludicrous one now.
