Vietnam War Facts:
Though the United States and South Vietnamese forces pushed back the Tet Offensive, the swiftness and ferocity of the attack led to a turn in popular opinion of the war in the United States. American citizens felt they had been misinformed of the true progress of the war, and that victory was not, in fact, within easy reach.
The guerrilla warfare that characterized the Vietnam War often resulted in civilian massacres, as it was difficult to distinguish friendly South Vietnamese from the Communist Viet Cong spread throughout the South.
Australia, New Zealand, and South Korea also sent troops to aid South Vietnam in their struggle against the North.
A 1980 Veterans Administration survey revealed that 82% of U.S. combatants in Vietnam felt that the war had been lost because the U.S. government had hamstrung their efforts, not allowing them to win.
