While the Saudi government has made a cursory effort to discourage such funding (only after pressure from the U. S. to stop it), Kuwait and Qatar have refused to so. Saudi Arabia's effort was the arrest of forty people who were members of a so-called charity that was funding terrorism, and a "religious decree" against supporting terror groups. Yessiree, THAT's taking it seriously for sure. Sort of like our "formal protests" against terrorist attacks against the U. S. over the past forty years, and we all know what that got us.
And just why do we continue to maintain friendly relations with Saudi Arabia? Glad you asked. The relationship between the U. S. is, in my opinion, a symbiotic one. We maintain a military presence there which bolsters their national defense in protecting their oil fields. Saudi Arabia is a very strategic location militarily speaking. In turn, Saudi Arabia "lets" us buy their oil from them.
This is all the more reason to drill here. America needs to get independent, or at least mostly independent of the terrorist oil nations. We have enough oil here to last us for many years. This would buy us enough time to allow the normal evolution of technology to develop alternative energy sources. The past 35 years has shown that you can't conserve your way out of a problem. While conservation and cutting waste (something Washington is DEFINITELY not into doing) are good and right things to do, they won't solve the problem. Increasing production here in the U. S. is the answer for the near future to allow technology to develop. We don't need to continue to be at the mercy of nations who only like what we give them, and we certainly don't need to keep on handing our money over to fund terrorist activities.
If we were to become independent of Middle East oil, I think we would see very quickly Saudi Arabia's true colors regarding the United States.
