Yep, that'd be my answer. Certainly the military action to date has been highly successful. The broader picture also looks good, but there are still some loose ends that could give us trouble. For example, although we got rid of Saddam's regime, we still need to replace it with something better. Otherwise, we may wind up back at square one. There are lots of ways this could still go wrong. We'll have to wait and see what happens.
Another loose thread is WMDs. The purported purpose of this war, at least at first, was to keep Iraq from supplying NBC weapons to terrorists. We have yet to find these weapons. If there weren't any, then the miliary action succeeded but there may be political cost to Bush. If the weapons were all destroyed shortly before the war, it's a clear win. If weapons have been hidden or exported, then we still risk failing to achieve our objective. Again, time will tell.
(And to pre-empt certain knee-jerk bashers, no I don't want the new Iraqi government to fail, and no I don't hope that terrorists get the WMDs just to make Bush look bad.)
