Yes, it is.
That is an explanation for why we got attacked.
It is not a justification for those attacks, and nowhere does he suggest we “deserved” or “invited” it as has been claimed.
It’s one thing to defeat your enemy from the outside. It’s another thing entirely, and often much more effective, to get inside his head, figure out why he does what he does, and use THAT to defeat him.
Well, it would have been real nice if when asked by a moderator if he was suggesting the United States invited the attacks, he simply said "no".
