In law, we often come upon a situation after an event -- a crime, an accident, etc. -- and we must decide what to do based on the knowledge we have now. Courts award damages based on the harm to the victim and the harm to society. Suppose you thought that the Iraq war was a mistake. If so, isn't the proper remedy to restore Saddam Hussein's family and the Baath Party to power in Iraq? If you are unwilling to consider that remedy, aren't you conceding that on balance, the benefits of the war outweigh the costs?I don't know whether to laugh or cry.
