It seems to me that the real enemies are hiding and we have to find them. We have to locate them and force them out into the open, trying not hurt any innocents in the process. The stated purpose is that we are ridding them of their mafia government so they can be a free and productive society of Iraqians, not to force them into bondage of the US. The people have had ample opportunity to flea to safety because we have allowed such time. We are getting rid of the termites, not the structure.
The people of Iraq have a responsibility to act on their own behalf. They are going to have to make their stand for freedom and independence. We are giving the people an opportunity, a chance, and if they want to live in freedom, they will support the ones trying to help them.
Perhaps Saddam and his loyalists will either attempt to escape or kill themselves, but they will do as much damage as possible in the meantime. I can't see them being taken as prisoners; it would be beneath their dignity and their religious convictions of martyrism.
