EXPLANATIONS BELOW
Concept note-1: -Communist forces ended the war by seizing control of South Vietnam in 1975, and the country was unified as the Socialist Republic of Vietnam the following year.
Concept note-2: -Finally, in January 1973, representatives of the United States, North and South Vietnam, and the Vietcong signed a peace agreement in Paris, ending the direct U.S. military involvement in the Vietnam War.
Concept note-3: -The remaining Americans escaped in a series of frantic air-and sealifts with Vietnamese friends and coworkers. A military government was instituted, and on July 2, 1976, the country was officially united as the Socialist Republic of Vietnam with its capital in Hanoi. Saigon was renamed Ho Chi Minh City.
Concept note-4: -The Army had to fight in unfamiliar territory, was lacking in moral, were not prepared for the conditions, could not shut down the Ho Chi Minh Trail, and were untrained to respond to guerilla warfare. This combination of disadvantages and the loss of public support led to the United States withdrawing from Vietnam.
Concept note-5: -In the end, even though the American effort to block a communist takeover failed, and North Vietnamese forces marched into Saigon in 1975, communism did not spread throughout the rest of Southeast Asia. With the exception of Laos and Cambodia, the nations of the region remained out of communist control.
