Though I support this war, there is one objection voiced by the anti-war people that lends serious thought.
Some oppose the war because it may lead to a broader war in the Middle East involving Iran, Israel, Syria, Turkey, the gulf states, the US, a new Kurdistan, Iraqi Shiites, etc. I doubt that a war with the United States could be any more damaging to the Iraqi people than Saddam's continued rule would be. But a broader war may cause more damage than a properly contained Saddam Hussein would. I think there are good arguments against the possibility of a bigger and broader war. The possibility is miniscule enough that I think it is worth the risk - this time. Mostly, this is because there is probably a greater chance that Saddam would start such a war himself later if he is left in power - especially if he is given the time to form alliances.
Yet the possibility of a broader war is a serious worry, and I am surprised that anti-war people don't often bring this up. Instead they spout innane babble about how "We are doing this for oil" or "Give inspections time to work".
Eventually, there will come a time when an unwise war will be proposed. Yet the peacenicks will have exhausted all there credibility by opposing such obviously neccesary conflicts as this one. They will be so used to not being listened to that they will not bother comming up with arguments that have any real chance of convincing a thinking person (I think they are dangerously close to this already). Since this war and so many before it would have gone off so successfully, Americans will begin to think that war can always be won quickly or easily. We will forget Vietnam. We will forget the human costs and the messy aftermath of even succesfull, neccesary wars like the first Gulf War and Afghanistan. Most importantly, they will forget the lessons of World War I.
World War I was started when a large power thought that a smaller power was supporting terrorism. It used this as a pretext for a war that drew in all the major European powers. Europe at that time did not have much living memory of any long wars in which millions were killed. The experience of the American Civil war was discounted because they thought Europeans could do it better.
Someday, the above-mentioned factors could America could fall into this trap. We will unnecesarily risk starting a World War II
scale conflict over some country's alleged support of terrorism. The peacenicks better start doing a better job reaching the public than they have been doing - because someday, they will be right and then we will need them. Let's go to war. We need to get that B*st*!rd. Yet even if we win, let us not let that experience make us forget what war is really like - or have any illusions that we can be sure of containing it.
