I don't like the idea of war. I know it's necessary in theory, because pacifism makes you a sitting target for people who know you're not willing to defend yourself. That doesn't mean I relish the thought of it.
In Iraq, I think it was based upon intelligence that was faulty. I think Bush thought in good faith that Saddam was developing weapons of mass destruction, and that left unabated those weapons would fall into the hands of terrorists and people that hated America. He made a tough call that may ultimately not have been the right one... but I don't know if there was a right call to make, because to do nothing when we're talking about a potential terrorist attack with WMD's is a sobering thought. If 9/11 was bad, you've got to realize just how much more devastating that would be.
And I think Bush thought that, independently of WMD considerations, a free Iraq (in the long run, mind you... countries don't develop a heritage of freedom and Democracy overnight) would be more stable, and a boon to the instability of the middle east. This objective will only be evaluatable in the context of history... will Iraq ultimately be free and gain stability, or will it devolve into Civil War? Will it become a breeding ground for Terrorists, or will it prosper and be an example to other countries of the region?
I think it's too early to look unbiasedly at the ramifications of this war, and we'll only be able to see if the objective of peace and freedom is reached over the long haul. I'm not a hawk, but I'm hopeful. I do think Bush acted in good faith with the American people in going into Iraq, given the context of 9/11 and the nature of Saddam's regime. But we'll just have to see with time whether this ends up being another Vietnam, of the beginning of something remarkable in the Middle East... and we don't have the perspective of history yet to shed light on that. In the darkest days of the Civil War, people weren't sure what they were fighting for or whether it was worth it... I for one, with the perspective of history, am glad Abe Lincoln kept the faith. I'm glad he refused to back down, and was willing to fight for a Union, with liberty and justice for all. That, in my opinion, is a dream worth fighting for.
