They preformed a special "Rain Prayer" (which is so different than a Raindance- raindances are fun and semi-naked!), and it failed. Why it failed, well, it could be because God already gave those people Oil up the ass and figured that this should make them shut the fuck up for a while, or it could be that the man is just too busy with war and genocide that he can't be bothered with a bunch of gulfies wanting some vanity rain. But that's my theory. Saudi clerics, on the other hand, blame it all-including the drought-on sinners , naturally! Ain't that nice?
