The thing about WWII is that we sat by on our own little continent, unwilling to help because we didn't see how the Nazi advance into Europe could actually come onto our territory. I can think about that with a little bit of disgust myself because ( As far as I'm aware ) we were the last ones to join into the fight and we still might not have if not for Pearl Harbor.
In Iraq, we went in with everyone telling us not to. There was no war already going on before we invaded a foreign country. There were no signs of that country planning an attack on us or on one of our allies. When questioned, we flip-flopped on several excuses for our actions before we finally decided on one, and that reason is still questionable.
Pearl Harbor was an attack made during a war, which is what it was whether we were actively involved in it at that point or not. 9/11 was a terrorist attack carried out by extremist religious fanatics during a period of what was otherwise peace.
Except for the fact that both were attacks of one form or another carried out against an otherwise unprepared United States of America on our own soil, there really is very little to compare between the two incidents.
That's just my opinion, I could be wrong.
To answer the question, no Luke, I don't think that makes you a hypocrite
