What the hell does it really matter if WMD is found or not. As long as the result is an Iraqi people free from fear and terroism, who can vote in free elections for the people of their choice. Can you imagine the terror they have lived with for thirty years and would have to live with for much longer if Saddam and family continue on. If you do not live under those conditions and want to prolong that agony you will say that dialogue will end it and there is no reason to go to war. Well dialogue did not end it in WW2 and only American, British, Canadian, NZ, Polish and Dutch blood did. The policy of liberate, rebuild and establish democracy worked then and it should work now.
And the U.S. has not taken any territory and kept it. Why would any one think we would start now. The troops we have stationed in other countrys are there with the agreement of that country. If they tell us to leave, we will. France did and we left.
Maybe this is the time to end all dictatorships and terrorism for once and for all time.
