The solution you refer to was chosen by Al Qaeda. It backfired pretty badly. It’s easy to scare hajis, but they’ll only stay scared for so long before brutality steels them against you.
Carthage it is, then.
Oh, and FYI, AQ applied “it” equally to women and children, non-combatant civilians, schools, hospitals, coffee shops, historical artifacts, artwork, musicians, doctors and teachers on and off the battlefield, 24/7/365.
Maybe that’s what you thought I was advocating, but it’s not, not even close.
