Mind-boggling isn't it?
not really.
they call for a global caliphate... so feature this: What is this piratical culture going to do when it can no longer feed off of productive societies???
First of all, they will revell /celebrate the rebirth of OAC’s camels in paradise and their achievement..... then realize there is no one left to feed off of and cannibalism will be the order of the day.
Islam never thought that far ahead.
