Joe Biden deserves plenty of blame for the moral atrocities happening in Afghanistan right now. His obstinate instance on pulling out of the country precipitously, against the advice of senior military advisors, is the proximate cause for today’s chaos. The disaster that followed wasn’t just predictable, it was repeatedly predicted. But anyone who tells you that Biden deserves all of the blame is trying to sell you something (probably a washed-up, has-been residing in South Florida). If Biden’s fecklessness was a necessary cause, it wasn’t a sufficient one.
