WHAT IS THE PROBABILITY THAT ONCE THE ANTI-MUSLIM RHETORIC CURRENTLY AIMED AT IRAN IS APPLIED TO SAUDI ARABIA AFTERWARDS?

Zero.

Why?

Because Saudi Arabia did 9/11, chops people's heads off in mass beheadings and is one of the alleged good guys.

On the other hand, Iran didn't do 9/11 and was and remains the main target of the subsequent wars and regime change.

All roads lead to 9/11.

Solve 9/11 and you solve the world.
