The US intervened in Vietnam due to a fear that if Communism took hold in Vietnam, Communism would spread throughout SE Asia.
The United States of America (USA), commonly referred to as the United States (US), America, or simply the States, is a federal republic consisting of 50 states, 16 territories, a federal district, and various overseas extraterritorial jurisdictions. The 48 contiguous states and the federal district of Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The country also has five populated and nine unpopulated territories in the Pacific and the Caribbean. At 3.79 million square miles (9.83 million km2) in total and with around 316 million people, the United States is the fourth-largest country by total area and third largest by population. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States is also extremely diverse, and it is home to a wide variety of wildlife.
Paleo-indians migrated from Asia to what is now the US mainland around 15,000 years ago, with European colonization beginning in the 16th century. The United States emerged from 13 British colonies located along the Atlantic seaboard. Disputes between Great Britain and these colonies led to the American Revolution. On July 4, 1776, delegates from the 13 colonies unanimously issued the Declaration of Independence. The ensuing war ended in 1783 with the recognition of independence of the United States from the Kingdom of Great Britain, and was the first successful war of independence against a European colonial empire. The current Constitution was adopted on September 17, 1787. The first 10 amendments, collectively named the Bill of Rights, were ratified in 1791 and guarantee many fundamental civil rights and freedoms. Military history by country

Political culture is defined by the International Encyclopedia of the Social Sciences as "the set of attitudes, beliefs and sentiments that give order and meaning to a political process and which provide the underlying assumptions and rules that govern behavior in the political system". It encompasses both the political ideals and operating norms of a polity. Political culture is thus the manifestation in aggregate form of the psychological and subjective dimensions of politics. A political culture is the product of both the collective history of a political system and the life histories of the members of the system and thus it is rooted equally in public events and private experience".
In the early 1960s, two Americans, Gabriel Almond and Sidney Verba, outlined three pure types of political culture in Great Britain that can combine to create civic culture. These three key features expressed by both men were composed to establish a link between the public and the government. The first of these features is "deference", which considers the concepts of respect, acknowledgment of "inferiority" or "superiority", and authority in society.
The domino theory existed from the 1950s to the 1980s. It was promoted at times by the United States government and speculated that if one state in a region came under the influence of communism, then the surrounding countries would follow in a domino effect. The domino theory was used by successive United States administrations during the Cold War to justify the need for American intervention around the world.
Referring to communism in Indochina, U.S. President Dwight D. Eisenhower put the theory into words during an April 7, 1954 news conference:
South Vietnam, officially the Republic of Vietnam, was a state which governed southern Vietnam until 1975. It received international recognition in 1949 as the "State of Vietnam" (1949–55), and later as the "Republic of Vietnam" (1955–75). Its capital was Saigon. The term "South Vietnam" became common usage in 1954, when the Geneva Conference partitioned Vietnam into communist and non-communist parts.
South Vietnam's origins can be traced to the French colony of Cochinchina, which consisted of the southern third of Vietnam and was a subdivision of French Indochina. After World War II, the Vietminh, led by Ho Chi Minh, proclaimed the establishment of a Communist nation in Hanoi. In 1949, non-communist Vietnamese politicians formed a rival government in Saigon led by former emperor Bảo Đại. Bảo Đại was deposed by Prime Minister Ngo Dinh Diem in 1955, who proclaimed himself president after a referendum. After Diem was deposed in a military coup in 1963, there was a series of short-lived military governments. General Nguyen Van Thieu led the country from 1967 until 1975. The Vietnam War began in 1959 with an uprising by Viet Cong forces supplied by North Vietnam. Fighting climaxed during the Tet Offensive of 1968, when there were over 1.5 million South Vietnamese soldiers and 500,000 U.S. soldiers in South Vietnam. Despite a peace treaty concluded in January 1973, fighting continued until the North Vietnamese army overran Saigon on 30 April 1975. Hospitality Recreation
