OBL was half Yemeni and half Syrian. The only reason why he even received Saudi Arabian nationality was due to his billionaire father's connections to the House of Saud and construction firm. Not to mention the fact that OBL became stateless back in 1994 as his Saudi Arabian nationality was annulled.

FBI and CIA already cleared KSA and concluded that there is no single evidence of Saudi Arabian involvement.
As for the 15 Saudi Arabian hijackers, most of Yemeni origin, so what? KSA had nothing to do with them. Not anymore than the US has anything to do with the 100's of American nationals who have joined ISIS, Al-Nusra and other groups in the Muslim world.
Anyway this law is not aimed at KSA nor will the victims of 9/11 receive a single penny.
In fact I believe that half of the world (almost) is entitled to sue the US for trillions due to their destruction of several countries from Vietnam, Afghanistan, Iraq etc.
Talk about desperation.
Anyway I do not care about the 9/11 the slightest. Yes, it was unfortunate but the US has committed 1000's upon 1000's of such 9/11's that receive no media exposure. In fact, if karma is the criteria, you deserve 1 million more of such incidents. Not even that number would make up for all the innocents that you have killed in the past 100 years across the world. ISIS, Al-Qaeda, let alone KSA, are angels in comparison. Anyway your time will come like that of everyone else. I would definitely support China and Russia against you in case of war and I hope that KSA will be on that side of the coin in the future, House of Saud or no House of Saud.
In fact I believe that the world and the Arab world should start arming African-Americas and Latinos who will become a majority in a few generations. Especially since 10% of all Latinos are of Arab origin.
Yes, and when the time of the House of Saud has expired, the Saudi Arabian public should sue the US for its support of that dynasty. As for those American companies, they should first learn how to pay their taxes abroad and stop cheating people.
Your elites have harmed the wold more than anyone else in the past many decades.
