I agree with much of what you say. It may be a pipe dream to think that Bush can bring peace to the region. You're right, but that should not stop him or the world from trying to bring peace. And the people that are against the attempt are the ones to look out for IMO. "Are we better off now. Do I feel safer."
Of course not there is a war going on. Of course things will get worse during a war. The coalition forces have captured or killed many terrorists. In the end I believe the world will be a safer place. This is providing the liberals in the US don't succeed with their propaganda and force a pull out of Iraq before it is stabilized. However as you know, there are no guarantees. But the free world has to try. IMO.
