Pussyfooting around with some low level jihadis in Iraq isn't going to solve the problem. The source of the poison is in Saudi Arabia. Specifically it's in Riyadh and Mecca.
Uh, not to put too fine an edge on it, but Saudi Arabia is an ally of the U.S.
They most decidedly are not an 'ally'.
Who funded the 9-11 killers? In no small part it was members of the Saudi royal family. They're thugs, killers, anti-christian, and vicious virulent anti-semites.
They're no more our friends than Hitlers government was to us in 1938.
