I suppose by your logic, Truman didn't end the war in Japan, since we still had people there for a while, and still do.
No, on Nixon's first day in office, the nearly half million troops that were in Vietnam didn't jump on a big aircraft carrier and head to San Francisco. We won't see that in Iraq either on Obama's first day. It's interesting I can be more accurate talking about the future, than you can be talking about the past. Nixon initiated a gradual withdrawal, with casualties dropping by more than half every year after 1968, according to your own linked statistics. We did rely more heavily on air power during that period. Nixon's actions brought an end to the Vietnam War. We were essentially done by the time he started his second term. The POW's came home in early 1973. Your take on history is like granny's from the Beverly Hillbillies, who insisted the Civil War was when The North invaded The United States of America.
BTW, about our previous conversation concerning Bush hiring telemarketers to slime McCain about his secret black daughter in the SC primary? Didn't happen. Those tapes you say you heard on a Dallas radio station--they don't exist. You may have been listening to a morning show. You don't have to have been in the radio biz, to know what happens on morning shows.
