This tries to look at the two different perceptions of the war. As read through it - really thought there was a 3d perception missing from it.... and that was of South Vietnam. Some might also look at the article and be thinking that there was a point about 1971 were maybe the switch was from an American war to a Vietnamese war and the perceptions were changed up. That all said - there were some interesting details of history in the article.
"Although the Vietnamese communist party was far from being a “monolithic decision-making body,” America perceived that it was the case. The discrepancy between those who favored the Southern violence and those who favored the Northern method widened coextensive with the widening of Sino-Soviet support. “Those who wanted to concentrate on the socialist development of North Vietnam” sided mostly with the Soviet Union and their “peaceful coexistence” while “those who wanted to wage revolutionary war in South Vietnam” sided with Mao and his protracted war."
