the americans could have done this very quickly, and they might have received some criticism for it from stupid people, but it would have been a smart thing to do and greatly benefited the region and the world. instead, they've done this the dumbest way possible by dragging it out as much as they can because they didn't want to do it at all, and now have an unavoidable, grueling, expensive, twenty year proxy war with the chinese in front of them that will distract them from other parts of the world and further ramp up their external debts.
this is the consequence of bad leadership.
