Nothing new, with a hint of self-interest bias from the bureaucracy and contractor side who would have preferred the status quo to go on, with all the spending and positions that it implied.
The conclusion is that the existence of Afghan government was based on US air support, flow of US money, and a hope that the former two will continue, giving some shade of stability.
Which is something, but if that is all there is to show after 20 years in terms of "nation building", that's a level of achievement to be expected after 2 years, not 20.
What is lacking there is an argument that it was within US interest to continue floating up the minimal stability of the notably useless Afghan government. Sure, things may go to shit, but whose problem is that? After all, none of US allies neighbor Afghanistan, its a gallery of enemies and frenemies instead.
