As dumb as it sounds, the FBI actually found and red flagged a few of the 9/11 terrorists months before the attack.

Of which the CIA, DoD, and White House convincently ignored.

I don't really think Israel set this up, but sometimes I wonder if there's intentional negligence because how else do you miss such a significant planned attack.

Although both could also be explained by bluffs. Maybe they really didn't think Hamas was actually going to go through with anything, especially since there was no building escalation.

Which would make sense because Mossad's intelligence is supposed to be world-renowned.
