Much more mild than my response. I'd summon him before me, burn a Koran on live Afghanistan television and then announce that for every death a mosque will be leveled. The first three have been picked and will be demolished in 15 minutes with high explosive munitions. Those in and around mosques might want to move away now, just in case their mosque was one that was randomly selected.
There's a reason why I'm usually the last one picked to play 'global leader.'
Eventually you get Moslems smart enough to show a little restraint and who understand “peaceable assembly.” Or, in a best case scenario, you run out of Moslems.
