Trespam: the phrase I use for Iraq before the current war is, "it was under military containment." That is, it was incapable of threatening us. Saddam's dictatorship, disgusting as it was, kept in check those elements that would have caused the chaos that is a favored nesting-place of terrorists. The UN inspectors were a tripwire against any moves toward external aggression. And our own Air Force (perhaps with allies at the time, I can't recall) was routinely taking out any of Saddam's installations that were seen as posing any threat whatsoever.
What we did, in Colin Powell's terms, was "break it." We broke open the walls and the slime oozed out all over the place, and festered and seethed and grew more infectious by the moment. And at the same time we missed the opportunity to help Afghanistan become the kind of example that would have inspired the region.
Maybe there's a way to rescue a more constructive outcome from the morass. Bush has four more years to prove his hypothesis. The world doesn't have to worry about another such US misadventure elsewhere; we've got our hands full with Iraq. In my opinion we should give Bush the leeway to follow through on his Iraq plans and see what happens. If he succeeds he will have overcome my scepticism, and any improvement in conditions in Iraq can only be good for the Iraqis.
