I totally agree that Iraq is better off without Saddam, and hopefully they will find themselves in a position in a few years where they have a stable, peaceful and free state, or states.
The problem I have here is a point of principle; I was taught that ends do not justify means. Yes, there are good things to come out of the war, but these by themselves do not make things right. And what about the three dozen or more other brutal dictatorships around the world? I don't think the US, or British or French or Israeli citizens, or anyone else for that matter, would put up with being the world's policeman, and indeed it isn't really any of our business, because where does it end ultimately? Do we go after any government we don't like the look of?
