Saudi Arabia and its regional allies could retaliate by removing billions from the US economy and restrict access to military bases if the American public are able to sue the puritanical kingdom for 9/11, according to experts.

“This should be clear to America and to the rest of the world. When one Gulf Cooperation Council (GCC) state is targeted unfairly, the others stand around it,” Abdulkhaleq Abdullah, a professor of political science at United Arab Emirates University, told Associated Press.

“All the states will stand by Saudi Arabia in every way possible.”

Congress overwhelmingly voted to override President Barack Obama’s veto of the bill that would allow Americans to potentially sue Saudi Arabia for 9/11. Lawmakers said their priority was not Saudi Arabia, but victims and families, RT reported.
