Ok, since you claim that we shouldn't go to war to minimize casualties, should we have gone to war with the Germans and turned the tide of the world wars? No, according to your philosophy.
Should we have gone to war for our independence? no, according to your philosophy.
So, by your philosophy, if it had been the one used by the presidents and our forefathers, we would still be a British colony, and Germany would have an empire larger than America, and we would be forced into war with them when they sent their fleets to American soil. So, by your philosophy, we would more than triple the casualties in World War 2.
Another thing, every soldier that is in Iraq VOLUNTEERED to return. Last I checked, the soldiers DON'T want to leave. Soldiers, in fact, are calling into American radio stations and saying what is really on their mind. One person called Chattanooga's 107.9 "The Duke," and said flat out that the polls were a complete and utter lie by the press to turn the nation against the president. THIS IS A WAR. THERE WILL BE RISKS. IF YOU ARE NOT WILLING TO GIVE YOUR LIFE FOR THE FREEDOM OF OTHERS, YOU MIGHT AS WELL SELL YOUR FLAG, BECAUSE YOU ARE NOT AN AMERICAN.
There, I am done yelling.
