9/11 is a good example of Saudi involvement in terrorism. I won’t say the Government was directly involved, but I wonder if the Saudi Government ever did enough to curb the money and Wahhabi extremism that supported terrorists. Thus, the echoes of terrorism are coming back to Saudi Arabia. I think this is a good time to tell the Saudis: “Ask not for whom the executioner’s blade falls, it falls for thee.”
IIRC they had some domestic rumblings 2-3 years ago. Seems quiet since then.
