Yes...We know that communism did not last very long but while it reigned and wherever it reigned its application resulted in misery and backwardness when compared to functional democracies. In the case of Viet Nam, if we examine the country as it is today with all the foreign investments that helped lift the country out of economic despair, we see that we are looking at South Viet Nam and why so many South Vietnamese defended their way of life, imperfect as it was, from an even worse fate -- communism. The argument that the Vietnamese communists was fighting for Vietnamese independence is a distraction. South Viet Nam was independent. As was North Viet Nam independent. So if Viet Nam today is working hard to become like South Viet Nam of yesterday, what was the war about? For what?
Same questions can be asked for China. What was the communist experience for? Independence? No...Because just like how the US view colonialism for Indochina...
Pentagon Papers, Gravel Edition, Summary and Chapter I
Roosevelt died before Indochina, which contained Viet Nam, Laos and Cambodia, entered UN trusteeship. Plus with the Ho-Sainteny Agreement in 1946 that the Viet Minh placed Viet Nam back under France, Indochina's freedom from warfare never had a start. So if we go by the America's attitude regarding colonialism in Indochina, that mean China's freedom from pre-WWII European colonialism was %99.999 assured. That mean the communist experiment and experience, in China and in Indochina, was unnecessary.
