In 2009, U.S. officials said Saudi Arabia was the “most significant source of funding to Sunni terrorist groups worldwide.” And in 2014, those same officials wrote that Qatar and Saudi Arabia were “providing clandestine financial and logistic support to [the Islamic State] and other radical Sunni groups.”

Bill is definitely going nowhere since US is in partnership with both Saudi Arabia and Isreal funding these groups to take down places like Lybia and Syria. AlQueda, AlNursra, ISIS are the "moderate rebels", many paid mercenaries that go to war for money.
