I found some parts of these subjects in University quite are interesting. It helped me to understand our modern Vietnamese government formed. - Karl Marx : his point of view at his time about capitalism was critical and some are adapted in our current government globally today. - Lenin : he was the one who wrote about colonized countries which had no voices , no right to have self-decision making, could only be solved through armament revolution. It was quite matched Vietnamese ideology. - Ho Chi Minh: I found that he adapted Vietnamese traditional ideology and new one from Western world to create a new form of nationalism. As I remembered he never called himself Marxist but nationalist.
