Kevin Drum has had it with pundits arguing that the withdrawal from Aghantistan damaged American "credibility."
The rest of the world doesn't believe in this alleged issue of credibility. They believe that the United States acts in its own self interest. We enter wars if we think they're in our interest. We leave wars if we think that's in our interest. And everyone knows we have the power to make our threats good if we feel like it. We hardly have to prove that more often than we already do.
