I believe the OSS working with Ho Chi Minh knew quite well who he was.
And as far as the US supporting those that “disposed of their political enemies quite ruthlessly”... that list would be pretty long and comprehensive, in just the 20th century alone. South VN pols were on that list too, as I recall.
And they were power-drunk, after having taken out a sitting president, and taking on the CIA with the Church Committee just before the final assault in ‘75. As far as the leftists labels - well, duh.
Of course they did. That Ho was fighting the Japanese during WWII is another of your irrelevancies.
You started with a defective argument here on these pages and I wager have not yet improved your position, at least with the readers.
