Fear or reward.
The North Vietnamese regard it as a war of liberation. The Americans saw it as a war against Communism. For them is was mostly a defensive and ´containment´ war, trying to keep the North Vietnamese from conquering South Vietnam.
The Vietcong, officially known as the National Front for the Liberation of South Vietnam, was primarily composed of communist sympathizers in South Vietnam, including members of the Communist Party of Vietnam and local peasants who opposed the U.S.-backed government. Key leaders included Ho Chi Minh, the North Vietnamese leader and a symbol of Vietnamese nationalism, and Võ Nguyên Giáp, a prominent military commander who played a crucial role in their guerrilla tactics and strategies during the Vietnam War.
There have been 22 organizations in as many countries since WW2 calling themselves "The National Liberation Front". Coming up with an original name apparently is not as easy as it looks. The mother of them all was the Viet Cong, composed of North Vietnamese and intended for the liberation and unification of Vietnam. It you are asking about one of the other 21, please specify.
North Vietnam aided Viet Cong or the National Liberation Front (NLF) in a guerilla war against the anti-communist. The army of the North was called People's Army of Vietnam or North Vietnamese Army.
The Tet Offensive was a military campaign during the Vietnam War that began on January 31, 1968 by the forces of the National Liberation Front for South Vietnam. The purpose was to displace the invading army presently stationed in South Vietnam and regain control of the country by the Vietnamese.
The National Liberation Front (NLF), commonly known as the Viet Cong, was a political and military organization in South Vietnam that aimed to overthrow the government and reunify Vietnam under communist rule. It was primarily led by communists and received significant support from North Vietnam, including military aid, resources, and personnel. Additionally, the NLF benefited from grassroots support among the South Vietnamese population, who were disillusioned with the existing government and its alignment with the United States.
Peasants
The role was the same for all peasants thru out time: provide the labor for the rulers (the rich) to make money. It happened to the English peasants, the Russian peasants, and the French peasants (in France)...and it happened in Vietnam (French Indochina). Peasants provide the labor force; the Colonial ruler provides the funding, organization, and the product.
Vietnam. Yes the yanks did get smashed by peasants, but as this ruined the entire country of Vietnam, no other country wanted to be like Vietnam.
They were draft age.
The Tiger, Water Buffalo and Dragon are the national animals of Vietnam.
Until the Vietnam War, few people ever heard of Vietnam. Therefore, Vietnam's sense of National Identity was STRONG.
