Unlike Korea, which is a peninsula, and could be isolated from enemy re-supply; Vietnam was NOT a peninsula and could not be isolated. Therefore, without invading (and ulitimately involving other countries) the US and it's allies could NOT stop the flow of men and material into South Vietnam. This was a scenario far an un-ending war. Consequently, the US and it's allies withdrew from the war, and the enemy proceded south, without the allies to stop them, and conquered South Vietnam. Actually the U.S. was ultimately defeated. They tried every tactic, from massive carpet bombing, to napalm to using agent orange and some DDT. The only thing we didn't use were nuclear weapons. There was no way to win, plus America had very little allies in Vietnam, nothing compared to the Allied turnout in Korea. The nation it self was not defeated, but rather the armed forces. We can call it a "withdrawal" all we want, it was still a defeat.
Because the war could NOT be isolated as the Korean War had been. Korea was fought on a peninsula, and was easily contained via the USN. Vietnam was not a peninsula, and in order to stop the flow of men and material into South Vietnam, the US would have had to expand the war into neutral countries (like Cambodia and Laos). Such an expansion may have drawn the US into conflict with the communist superpowers...as did happen in the Korean War. Therefore, it was either expand the war (make the war bigger); or simply end it, by leaving.
The French were defeated in the Dien Bien Phu battle in 1954. They were driven out then.
North defeated the South.
We don't have your list of descriptions and can't answer the question.
The Vietnam War=the military draft!
The French fought there from 1946-1954, and were defeated in what was later called North Vietnam at a place called Dien Bien Phu in 1954. Thus ending the war.
They had been militarily defeated. There was no place left to fight over.
Military advisors first arrived in Vietnam in 1950. America started sending troops into Vietnam as early as 1960, but they took no military action until 1965. The United States was actively (militarily) involved in the Vietnam War from 1965 to 1975.
North Vietnamese won the Vietnam War, and it is the year 1975, not 1990, that they militarily defeat South Vietnam.
The Seljuks were defeated militarily, primarily by the Khwarezmian Empire (which was based in Persia).
Militarily, the forces of North Vietnam (including South Vietnamese sympathizers known as the Viet Cong) were the only units fighting against the U.S. China and Russia both provided material support to the Hanoi government.
Historians generally agree, that 1961 was the year in which the US became militarily involved in Vietnam. History may require a re-visit in this instance.
Bolívar ran away, to live to fight on another day.
Communist North Vietnam defeated South Vietnam
The nation (country) of Vietnam didn't exist during the Vietnam War. Nor was any nation called "Vietnam" fighting the US. There was a country called North Vietnam that defeated the Republic of South Vietnam in 1975. The US was allied to the RVN (Republic of South Vietnam).
North Vietnam defeated the South (or the North conquered the South).
