and don’t stop until you catch your tail

That droll Mr Bush recently said it would be bad to stop killing people and breaking stuff in Iraq before “the mission” is completed. Say what? I thought the mission was to take Saddam’s nukes and war-germs and bad chemicals away from him, and cut off his support for al-Qaeda; well, that was accomplished quite a while ago. So what’s the mission now? To find a retroactive justification for the invasion?
