Two years ago, this, in a few words, is what "Support the War" meant to me: go in - eliminate Saddam and his command and control apparatus - check everywhere for purported WMDs - get out. If WMD's are later interpreted as al-Qaeda, then our current level of effort and strategy have failed and will fail. The undeniable "civil war" between Sunni and Shia was going on since well before the US arrived. Saddam merely suppressed it. We don't have the will or insight to effectively suppress the fighting rabid dogs that Saddam had. We have no business being there anymore. We need to learn tons more about our enemy before we commit continuing and increasingly misdirected resources toward the fight. The worn belief that we will have left a nation in tatters and "someone else" will fill the vacuum as an excuse to remain is unhelpful and irrelevant. That attitude is just part of our unhealthy national "bleeding heart" syndrome - our liberal and ego-centric belief that we are responsible for all the worlds ills.
When we feel our national security is threatened, we need to do what we do best: Go in, get it done, and get out. Lingering around to patch up the mess, most of it what we did NOT create, is just feeling too guilty for our own good.
