We lost the war because of America's foreign policy. It was to stop the spread of Communism, not do be rid of it. They would have been able to destroy Communism in many different times like the Korean War. Lyndon B. Johnson didn't want to be rid of Communism because that would make us sound like an Empire again like with the Philipines in the Spanish American War and right now in Iraq. We lost the war because of forfeit. Johnson said no to being rid of Communism like Truman said no to McArthur in the Korean War. We had an open door and a 100% chance of destroying Communism, but we didn't have the permission.
The United States did lose the Vietnam War. They were not able to overthrow communism which was their aim as presented to the public. Pulling out is a loose term for admitting defeat. The VC were vastly superior in their tactics and numbers. They had cause to be at war, many of the GI's believed Americans did not. There is no denying it, America lost the Vietnam War.
The United States pulled out of the Vietnam war. We did not lose it. Technically, we were not at war, we were advisors but the Congressional approval to fight in Vietnam was not given. If anyone lost it was the people of Laos and Cambodia who came under Communist rule after the war.
Lack of interest. No one was that interested in stopping the Communists agression in the Far East. And as the war went on the cost in blood & treasure seemed extreme and fruitless. Didn't lose,just withdrew. We could have won a better deal on tungsten,rubber,chromium,China containment,security. You can't please everyone, but it helps. Kept going that long with the support of China, Russia & the U.S. allies. + the draft was ended c. 1970 that made the war more tolerable; then war crimes & napalm tuned off the rest.
The only reason the US lost was because we withdrew from there. The US won every battle but the Vietnamese were willing to sacrifice many more lives than the US.
They lost because the politicians did not let the military do their job. They made decisions that should have been made by generals. Politicians should not make tactical decisions.
The people of South Vietnam did not want to fight that war and the U.S.A. didn't want to fight that whole war for them without much help from them.
Some of these answers are so deluded. America lost the war in vietnam for various reasons. A few of the reasons are listed below, providing some idea of what happened in Vietnam even if it is a shallow overview: The US troops completely underestimated the VC,who were skilled jungle fighters, and also had mass peasant support. The American tactic 'search and destroy' increased VC support. As one soldier said "If they weren�t VC before we got there, they sure as hell were by the time we left"
