Gees talk about not knowing your history. Why open your mouth when you have no clue?
You need to read up on your history. Nixon pulled out the troops in 73, and called it "Peace with Honor". Kissenger even accepted the Nobel Peace Prize for this action. If you read up on Nixon and the Vietnam war you will find that Nixon's main objective for the war was to not be blamed for losing it and they were secretly negotiating with N Vietnam for a way to pull the troops out "with honor" from the very start of his first term. Nixon never believed we would win this war.
