Just watched a first episode on netflix, about the war... Had a good few gins and seemed very complicated how it all came about.
The French and the Japanese? Wanted to take control.... How and why did America get so involved?
The Vietnam War started as a result of the mess left over by the First Indochina War, during which the French fought against the Communist-led Viet Minh.
After going full Communist, North Vietnam instigated a civil war in South Vietnam. The Americans got spooked, believing that if the entire country fell to Communism, this could cause a domino effect in the region. So they went over there to sort it out (and failed).
The Americans needed local support, so they asked Australia to join the war, which we did (to our lasting shame). Incredibly, many Americans (if not most) remain ignorant of Australia's role in Vietnam.
Did Vietnam atually win the war?....
North Vietnam won the war, albeit at a terrible cost. South Vietnam lost, and was subsequently absorbed into what is now the Socialist Republic of Vietnam.
I just can't get my head round how the USA didn't beat them so easily
Many reasons; I'll only list the main ones.
Firstly, it was a highly unconventional war. The Americans were faced with guerilla warfare in jungle terrain, so they were unable to take full advantage of numbers and technology. They also suffered from the fact that their soldiers had only received basic training for this type of combat. By contrast, Australian troops had been extensively trained for this scenario, and proved extremely effective.
Secondly, North Vietnam was supported by the USSR, China, North Korea, and foreign militia (e.g. Pathet Lao and Khmer Rouge). In many ways it was a proxy war, typical of the Cold War era.
Thirdly, it was a very distant war with challenging logistics. Nowhere near as simple as WWII, in which the primary theatres were far more accessible.
Fourthly, public opinion turned against the war very quickly, and this resulted in political pressure to end it. The Americans introduced conscription to maintain troop numbers, which didn't go down well either.
