It's typical of Obama's leadership that he takes orders from the Saudis. I do recall him bowing before the Saudi king, so maybe that has something to do with it.
The Saudi's regard us no differently than they do their house servants. We are there to do things they prefer not to dirty their dainty hands with. Like killing Syrians. How many troops have they committed? How many sorties is their air force flying? Financing ISIS and al qaeda really doesn't count as "helping", even though they have put a lot into both organizations.
How many Syrian refugees have the Saudis and other wealthy gulf states taken in?
