What is the difference between the Viet Cong and North Vietnamese?
There is no difference. The North Vietnamese were Vietnamese, So were the Vietcong. The Viet Cong, a politico-military organizations in southern Vietnam after being divided in 1954, and included those who were opposed to Ngo Dinh Diem was corrupt dictatorship. The Vietnamese had the Vietnam People’s Army (called “ANB” by the Americans), but the Vietcong was a pejorative name given to the Vietnamese communists who organized and fought the ARVN (Army of Vietnam repulica) in the south, and soldiers in northern Vietnam are often sent to reinforce units of South Viet Cong. If you can ignore the artificial separation policy of Viet Nam in “North” and “South” – One will realize that both the Viet Cong and North Vietnamese were all Vietnamese people.
