I think we’re about 8 years overdue to get out of Afghanistan, but I can agree with much of that.
We should have left immediately after the punitive expedition phase, and before the meals on wheels phase. Said “Do it again and we’ll screw you up worse, we’re outta here” and decamped.
Actually, I agree with you. We probably should have declared victory and then left with just the capability to intervene if and when we had to in 2002. Leave the Afghans and Pakistanis to fight it out and figure it out for themselves.
