They had several stockpiles, including actual fucking short-range missiles. Didn't help them at all against a modern military force, did it? But you think the US Army is concerned about Bubba and his cache of AR-15s?
US Army continues to struggle to control Afghanistan. Russians failed to control.
The Soviet Union at least had the excuse of having a conscript army and America arming the Afghanis with MANPADS. America's failure probably had more to do with nobody having any clue what the actual objective was.
you're not wrong.
Everyone has struggled to control Afghanistan, including every Afghan government in history. Not going to hold it against them for doing better than most at the task, but not expecting control given the nature of the task and territory.
Sometimes "Bubba" is in the US Army. And yeah, the US Army is concerned about him.
