"The Saudis deny any role in 9/11, but the CIA in one memo reportedly found "incontrovertible evidence" that Saudi government officials — not just wealthy Saudi hardliners, but high-level diplomats and intelligence officers employed by the kingdom — helped the hijackers both financially and logistically. The intelligence files cited in the report directly implicate the Saudi embassy in Washington and consulate in Los Angeles in the attacks, making 9/11 not just an act of terrorism, but an act of war."
