So is there no credibility to the idea that Trump's actions were the cause?
I mean it was a Trump platform to bring troops home. It could have been predicted that pulling troops out would cause a collapse, because that should be expected unless you are really optimistic or know something I don't. So Biden getting the hot potato seems like a half reasonable take. I don't think the TaliBlitz was forseen or seen as likely scenario, so maybe the collapse was full-speed instead of the expected slow-motion. It's still embarrassing to engage in public inter-administration finger pointing but did everyone expect withdrawing from AG to go well?
I'm almost positive we discussed it here under Trump, and also almost positive that while I was for pulling out, I dinged Trump regarding the accelerated timetable he wanted over a lengthier pullout in stages. That, of course, might have only prolonged the inevitable.
There may simply not be any methodology for a US pullout that doesn't result in what we see now. Perhaps a longer term pullout might have allowed us to bring some equipment home, though it sounds like we were fine leaving it all there.
At any rate, I think one of the main points now regarding why people are "picking on" Biden is that he is a deer in the headlights, and both the President and VP seem to be hiding out. I guarantee Trump would have made several statements by now, regardless if they would have been popular.
