All that and no room for any mooselimb refugees.
For all the insinuations about nukes/Mecca here, keep in mind that Iran(Persia)and Turkey hate the Saudi Royals and likely will take them out, and sooner than most expect. The Gulf States will crumble and a Grand Caliphate can form without Saudi influence.
ISIS is a temporary distraction.
Turkey and Persia can unite (despite Sunni/Shia) against common enemies such as Kurds, then ISIS.
The rest of Islam will rally around the strong horse.
Destroying mecca would not just bring down the sunni - it would destroy the entire islamic belief system.
Persians and Turks hate each both on a religious Sinn/Sian and on an ethnic basis - barbarian Turk vs ancient culture Persian.
The rest of Islam will rally around the strong horse to keep their families, friends and themselves from being slaughtered.
