What i’m wondering about it how they got from “Why not bomb Mecca?” to “Why not nuke Mecca?”, unless that’s what he actually said, it’s being taken out of context. You could order a precision stealth bomber strike on the most important target, or carpet bomb the whole city, you wouldn’t need a nuke to do that.
EDIT: I see that he was responding to a question about a nuclear attack, so they were right. Still, it’s common to see muslims go nuts because someone said one bad thing about them or their religion, see those cartoons about muhammed or the recent south park episodes. Calling for people to kill others simply because they show your prophet isn’t the best way to maintain a relationship with others.
