I don't think that anybody could have predicted that these people would take an airplane and slam it into the World Trade Center, take another one and slam it into the Pentagon, that they would try to use an airplane as a missile.
I don't think anybody could have predicted that they would try to use an airplane as a missile, a hijacked airplane as a missile.
Oh, indeed there is a tie between Iraq and what happened on 9/11. It's not that Saddam Hussein was somehow himself and his regime involved in 9/11, but, if you think about what caused 9/11, it is the rise of ideologies of hatred that lead people to drive airplanes into buildings in New York.
