Makes no sense.So do what the CIA does in other countries but with less subtlety?
CIA can't muster troops, even military intelligence, the most they can do is clandestine operations (strike teams) and financing local groups. This suggestion is wiping organized crime in Mexico and allowing those people displaced by it to return home. It requires a large-scale, internationally legal (hence going through the Mexican government and the UN) operation and hopefully cooperative with the local military and police that aren't compromised.
