Yeah, not really one of his better quotes. A paraphrase might be:
Let's go in there and crush the standing army but fail to have an actual plan for managing the peace. Then, when the country is really screwed up and becoming a terrorist-magnet, let's hand it off to the UN so we can blame them for the increasingly likely miserable outcome, especially if large-scale bloodshed then ensues. It will be very important to do this if it looks like more people are dying in the instability than they were under Saddam Hussein.
