Replace the A-10s with crop dusters carrying Roundup insecticide and spray every opium field that we can find.
You know, there’s also one other very big advantage to getting out of Afghanistan -
currently, it’s surrounded by countries hostile / unwilling to help NATO there .... so every single supply must be flown or trucked in via Pakistan - and Pakistan is exploiting that fact to the max, including playing fast and loose with the Taliban, because they know they have us by the short hairs.
So getting out of Afghanistan allows us to finally tell Pakistan to go to hell and put the screws to those backstabbing bastards.
(and we could probably get a lot of help from India on that one)
