My reference was to 1919; anything you post about subsequent events has no bearing on the discussion. I am no fan of Ho Chi Minh; he can rot in Hell with Stalin, Mao, and co.
I will grant that in 1919, the World Communist movement was just starting to get organized, the Soviet Union was still knee-deep in Civil War, and certainly the fight against colonialism back then, was one of the things that gave Communism some traction. But by the end of WWII, Ho was firmly in the Soviet Camp, and would have established a Communist dictatorship, with or without the help of the US.
