Why don't liberals understand that without the Iraq war, we never would have caught bin Laden?

I am a liberal and I love America. I think the president misled us all on the reasons why we should have invaded Iraq. I think the world is better off without him but as for the reasons we went in, they are all a bunch of crap. I think this is the best country in the world. I think that its about damn time we started acting like the leader we are, especially morally, and that means not misleading people with false information that gets a lot of countries other than just ours into a war.
