I don't believe I've ever stated a posture on the Iraq war, though at the time it was going on it was very unpopular in my country. I have a negative impression of it (because I distrust your President), but I don't pretend to be informed enough to have a valid opinion.
But leaving the means aside for a second, the end (or this particular end, I don't know anything about Iraq's current situation) is possitive under all points of view.
