In hindsight, giving automatic weaponry to batshit insane religious sect just to troll your competition may or may not backfire. My question is, who would've thunk it?
Hindsight is 20/20, but stupidity is always blind.
Give Afghanistan weapons to fight our enemy. Afghans later use said weapons to fight against the U.S.
Give Iraq weapons to fight our enemy. Iraqis later use said weapons to fight against the U.S.
Doing the same exact thing over and over, and expecting different results.
