If you look at it this way, we're acting in accordance with our own definitions... but what about in the view of others.
For instance, we look at other religions that are non-Christian and call them cults. What about those who are non-Christians? How do they perceive us? We could be considered cults to other religions.
Back to the war in Iraq... who started? I don't remember Saddam starting anything. I haven't seen anything that appears as if Saddam launched a rocket against us, sent bombers against us, sent ships after us... nothing.
Think of it this way. You and me are enemies. I don't like how you do things. You don't like how I do things. However, I punch you in the face. When people ask me why I punched you in the face, my defense would be... "He/She was gonna hit me."
That's what Bush has done. "Iraq was gonna do something bad to us. So, I had to hit Iraq first."
Now, doesn't that comment sound a bit... childish?
