No, but it was primarily because a bunch of a**holes in the state department were all too happy to let some questionable saudi “students” into the country.
Actually, 9/11 happened because a bunch Islamo-Nazis decided to murder Americans.
It no longer matters what we believe. What matters is what they believe and we must have a President who will defend the nation. RuPaul is not that guy.
I think the problem that resulted in 9-11 was even more mundane that you imply. The Associate Attorney General promulgated rules for the CIA to not interface with the FBI, in order to protect the privacy of persons in the U.S. Because of this wall of separation, intelligence that we had was not acted upon by the FBI. Imagine how differently the century might have been if Bush didn’t go down the rabbit hole that Iraq turned out to be? But, my goodness, 9-11 turned everything around. Where he and Condi Rice had made it clear, in 2000, that we should avoid getting involved in nation-building, there we were, just a few years later, trying to re-construct two nations, one of which never was a nation in the first place.
