Vietnam War: Causes, Timeline, and Impact

The Vietnam War

The Indochina Peninsula was a French colony. France withdrew from the area after a long war, culminating in defeat. The Geneva Accords of 1954 left Vietnam divided into two states: North Vietnam, with a communist regime led by Ho Chi Minh, and South Vietnam, ruled by a pro-Western dictatorship prompted by Ngo Dinh Diem. These agreements established an interim dividing line between North and South at the 17th parallel and provided for the reunification of the country after elections.

In South Vietnam, there was a communist guerrilla group, the Viet Cong, supported by the North Vietnamese regime. The U.S. government decided to support the South Vietnamese regime, fearing that the Viet Cong would impose communism throughout the country. The conflict in Southeast Asia occurred in the context of the Cold War, aiming to prevent the progression of communism in Asia. The US wanted to avoid what was called the domino effect, i.e., a successful communist revolution in one country setting an example for the dissemination of pro-Soviet governments in neighboring countries.

The United States' direct armed intervention began in 1964, with troop levels exceeding 500,000 by 1968. However, this proved ineffective: neither the steady increase of troops, nor the technological superiority, including attacks with chemical weapons, nor the massive bombing of the North, managed to subdue an enemy that used guerrilla tactics and had significant popular support.

The Tet Offensive and US Withdrawal

In 1968, the Viet Cong launched an offensive that demonstrated the inability of U.S. troops to win the war. Additionally, opposition to the conflict had spread throughout the West, even within the United States, due to the terrible television pictures shown. In 1969, Richard Nixon assumed the U.S. presidency with a promise to end the war, and from then on began a gradual withdrawal of troops over four years.

In 1973, a ceasefire agreement was reached in Paris. The United States withdrew its troops and agreed to the reunification of Vietnam, but the struggle between North and South continued until April 1975, when troops of the Viet Cong and North Vietnamese took Saigon. In 1976, North and South Vietnam unified to form the Socialist Republic of Vietnam, which immediately joined the pro-Soviet bloc. Around the same time, the neighboring countries of Laos and Cambodia, which had been involved in the conflict since 1965, fell into the Soviet orbit.

Consequences of the War

The Vietnam War resulted in an enormous loss of international prestige for the United States and a significant military failure, at a cost of more than 58,000 U.S. soldiers killed and 150,000 wounded. It is considered the greatest military defeat in the history of that country, and since then, successive governments have limited military interventions abroad.
