Trump last night said we would no longer be nation-building but killing terrorists in Afghanistan going forward. Oddly, several years ago I heard from a general departing to lead Americans in Afghanistan that we were failures at nation-building there, but good at killing.

Sorry folks. America has been trying to nation-build in Afghanistan for 16 years, and in Iraq (how did that go?) and in Vietnam before that (we know how that ended.) It has been about nation-building all along, and that has failed time after time. Despite what Trump said last night, it is still about nation-building in Afghanistan and Pakistan today.

Are we good at killing? Yes. Are we wasting another generation of young American troops in another fruitless war? Yes.  Are we protecting the American way of life in the process? No. Are we wasting more billions, even trillions, that could be used to rebuild our own nation? Yes.

Are we learning anything? Yes. Are we doing anything useful with that learning? Absolutely not. Thanks Trump. The one time where one of your bad ideas — getting out of Afghanistan — might have been positive, you failed us again last night.
