re: Dumb question, I know, but is Islam a form of Christianity?

K, so you pettily destroyed Mecca and sent it's ashes to the wind?

One billion people aren't going to convert and/or see the error of their ways. We'd have kicked the hornet's nest so hard that nests of other hornets that all hate each other swarm together for once.

Take down militant leaders that step out of lime as they arise, let em kill each other, heavily monitor anyone trying to come around to the places that matter, and we're mostly good.
