The american people did.Not only did he not end the war he was the bastard who got us into it in the first place despite what our corrupt school system tells us.read below. The Vietnam War The Vietnam War of 1964-1975: Although history puts America's war in Vietnam in the "lose" column, the United States actually won every major conflict including the infamous Tet offensive. The demise of the United State's presence and power in Vietnam was not due to losses on the battlefields but to the loss of support of the American public. The North Vietnamese were unified in their determination to win and America was not. For America it was a limited war and for the Vietnamese it was all out war in defending their homeland against American aggression. The Americans underestimated the resolve of the Vietnamese who had for hundreds of years already had been fighting off the Chinese, then the French and now the Americans. They were not about to give up. President Johnson could not put everything into the war because of the fear that the Chinese, which had also got involved with the Korean war would get involved, or even Russia. So it was a half way effort doomed to failure. In Vietnam it is called the American war. It was an immoral war that the intellectuals and newly enlightened young people of America just could not accept. The duped older generation that remembered the glory days of U.S action in WWII just could not accept the truth of what was really happening there. Calling the war a "police action" was just another lie to hide the fact that it was an illegal war as well as immoral. President Johnson escalated the conflict to a murderous campaign of American aggression with intense bombing of neighboring countries. Most people think that Richard Nixon got us out of Vietnam. The fact is that it was Nixon that got us into the war while Vice President under Dwight Eisenhower and it was the American people that got us out. If it was up to Nixon, he would have carried out his campaign of terror in Vietnam until he stepped out of office. I always knew it was the american people who ended it,this just confirms it.
