Correct. We can't save everyone in the world from the bad people they live with. The problem is that by the actions of 20 yrs we were the ones that put them in peril in the first place which does generate a higher level of responsibility, but even given that, the US does in the end have to extricate itself from policies that were a mistake in the first place and can't be fixed and if there were ever any easy way to do that in a place it means the policy probably wasn't a mistake and the need would never have arisien. The responsibility for the exit failures in Afghanistan may be Biden's but also to just as great an extent, Bush's, Obama's and Trump's. Biden may have been the one write to the check, but he was fundamentally paying off the bill run up by others.
