I am also not fully sold on the idea that getting out is a good idea, but for different reasons. The growth of Afghanistan's economy (300-400% GDP) and the quality of life improvements since the Taliban were removed has been notable, and if this regresses then there will be a real human toll.

But not pulling out seems to be just delaying the inevitable, and a continued presence is expensive and arguably incendiary/destabilizing to the whole region, so I can understand doing it.

This isn't a commentary on the specifics of how it was done, merely on whether a withdrawal should have been done.
