Saudi will fight ISIS, their creation? Right. Sure they will. No doubt the they are really going in at the behest of Obama to fight the Shi'ite Assad. Incidentally, the Saudis are one of the most worthless Armies in the entire world. A bunch of ragamuffins in Yemen are whooping their arses and Assad/Putin will deliver even worse. Of course, it's obvious that this is a panicked reaction to Assad's recapturing Aleppo and is occurring solely provide some Arab cover to Obama's manic & obsessive quest to over throw Assad.
