Historically governments did not have the weapons we have that can destroy tribal warriors. “Oh they hide in the mountains”. But we both know we could still kill them there easily if we chose to.
We still, iirc, manufacture napalm.
Some time ago, I suggested a late night well-timed criss cross flight of all pockets of resistance delivering napalm. No time to alert the other pockets.
At least there would be no lingering messes, like the Soviet’s use of bioweapons.
