What Caused the Vietnam War?

Also known as the Second Indochina War, the Vietnam War was a long and bloody conflict, spanning 20 years from 1955 to 1975. 

The war was primarily a clash of ideologies between the communist government of North Vietnam and the capitalist government of South Vietnam.

Throughout the war and the events leading up to it, the North Vietnam government had the support of allies in the south known as the Viet Cong. 

Meanwhile, the South Vietnam government had the support of the United States and other anti-communist allies.

The war was also known as the “American War” in Vietnam. It led to immense destruction and loss of life. 

Estimates suggest that it resulted in around 3.8 million casualties, and not all of them were military personnel.

Though the Vietnam War ended decades ago, it remains entombed in history and people’s memories. It was the longest war in US history and one of the most unpopular for several reasons. 

What were the events that led to it? By revisiting what took place, we can avoid becoming involved in another catastrophic conflict like it in the future.

Historical Background of the Vietnam War

Vietnam had been under colonial rule since the 19th century. Initially, the French Union ruled the nation until Ho Chi Minh’s Viet Minh movement overthrew them after being defeated in the bloody Battle of Dien Bien Phu in 1954. As a result, the French and Vietnamese signed a peace agreement at the Geneva Conference. 

This agreement divided Vietnam into the communist-led North and the anti-communist South. 

The agreement stipulated that elections would be held in 1956 to reunite the country, but they were never held. 

Instead, the United States started sending military aid and advisers to the government of South Vietnam to support its anti-communist agenda against the North.

Causes of the Vietnam War

The Vietnam War was the culmination of different conflicts across several governments:

  • The Cold War between the United States and the Soviet Union
  • The Gulf of Tonkin incident
  • The Diem Regime and South Vietnamese politics

The Cold War and the Domino Theory

The Cold War emerged as part of a broader global struggle for power between the United States and the Soviet Union, the two superpowers after World War II.

The geopolitical and ideological tensions of the Cold War thus shaped the Vietnam War as the two countries had fundamentally different beliefs.

The United States advocated a global system of free markets, democracy, and individual liberty. Meanwhile, the Soviet Union promoted the spread of communism and the establishment of social states.

These conflicting visions led to confrontations between the two nations, with both sides seeking to spread their ideologies and influence. This resulted in a series of proxy wars which led to global conflicts.

The United States saw the spread of communism as a direct threat to its security and interests. 

The government feared that if South Vietnam fell to the communists, all of Southeast Asia would end up adhering to communist ideals. Known as the “domino theory,” it was the United States’ primary justification for its involvement in the Vietnam War.

The Cold War also influenced US strategies and tactics. The US government decided that withdrawing their support and cutting off supplies from the Soviet Union and China were key to defeating communist forces in Vietnam. 

They thus launched a large-scale bombing campaign against North Vietnam to destroy the county’s infrastructure and disrupt its supply lines. They also heavily relied on covert operations and assassinations to mitigate the spread of communism.

The Gulf of Tonkin Incident

The Gulf of Tonkin incident was a pivotal event. It involved two separate incidents that the United States used as a pretext to escalate its involvement in the war further.

The first incident took place in early August 1964 when the USS Maddox, a US Navy destroyer, was conducting a reconnaissance mission in the Gulf of Tonkin off the coast of North Vietnam. 

Three torpedo boats from the North Vietnamese Navy intercepted the Maddox, who opened fire at the vessel. The Maddox fired back, and the torpedo boats eventually withdrew.

The second incident was more controversial and occurred two days after the first when The Maddox and USS Turner Joy, another US vessel, were reportedly attacked by North Vietnamese Navy vessels. 

The US government used it to justify escalating the war, employing a retaliatory strike against North Vietnamese targets. Meanwhile, Congress authorized military force in Vietnam without formally declaring war. 

This was sanctioned by the Gulf of Tonkin Resolution, despite the fact that the second attack may not have occurred at all. It is believed that weather conditions or electronic malfunctions likely caused the radar signals that were first interpreted as an attack.

This incident was a turning point in history as the US used it to justify its growing involvement in the Vietnam War. But it also fueled the American public’s opposition to their government’s response.

The Diem Regime and South Vietnamese Politics

The Diem Regime was established in South Vietnam in 1955 after the country was partitioned in accordance with the Geneva Accords. Ngo Dinh Diem, the regime’s leader, established a dictatorship and used brutal force to suppress political dissent.

Diem’s capitalist, anti-Buddhist policies alienated South Vietnam, particularly rural peasants. They were unhappy with his land reform policies because they favored large landowners and corporations. 

People also resented his close ties with the United States, which they viewed as an interfering force in the country’s private affairs.

The government’s corruption and inefficiency led to widespread dissatisfaction while the communist insurgency grew stronger. As a result, the US has become increasingly involved in South Vietnamese politics, providing economic and military aid to suppress communist powers. 

This further raised concerns about the regime’s human rights violations and inability to govern the country effectively.

After years of mounting opposition and growing dissatisfaction, Diem was overthrown by Vietnamese military officers. The US government, which had become disillusioned with Diem’s leadership, supported them. 

Despite the coup, the country was still mired in political instability and conflict, which was another factor that escalated the Vietnam War.

Consequences of the War

The Vietnam War had far-reaching consequences:

Human Costs

The Vietnam War was a brutal and protracted conflict that killed millions, including soldiers and civilians. 

Estimates of the total casualties vary, but it is believed to be between 1.5 and 3.5 million Vietnamese people. In addition, over 58,000 US troops and thousands of soldiers from other countries were also lost in the war. 

It caused widespread displacement as millions fled their homes and sought refuge. 

Political Consequences

The Vietnam War had significant political consequences domestically and internationally. The war had become a deeply divisive issue in the United States, with many people protesting against US involvement. 

The war also led to a loss of confidence in the US government and its military as the public became disillusioned at how their government handled the conflict. 

On an international level, the war damaged the reputation of the United States. Many people around the world saw the country as an aggressor.

Economic Consequences

The Vietnam War was an expensive conflict. The US government spent billions of dollars on military operations and aid to South Vietnam. 

The cost of the war had a significant impact on the US economy, contributing to inflation and other economic problems. The war also had a devastating impact on Vietnam’s economy, which was left in ruins.

Environmental Consequences

The Vietnam War had a significant impact on the environment, particularly in areas where heavy fighting took place. 

Using chemical weapons, such as Agent Orange and napalm, caused widespread damage to Vietnam’s landscape. They contaminated soil and water sources. 

The war also led to deforestation, soil erosion, and other environmental degradation that concern ecologists today.

Legacy of Trauma

The Vietnam War left a lasting legacy of trauma and pain for the people who lived through the conflict and subsequent generations. Many people who fought in the war and their families continue to suffer from its physical and psychological wounds. 

The war also profoundly impacted Vietnamese society, with many people still grappling with its social and economic consequences. It also led to an epidemic of chronic PTSD among survivors.

Shifts in Global Power

After the United States lost the Vietnam War, there was a significant shift in the global power balance. 

Most notably, the US began to lose its status as a powerful global force. Its loss demonstrated that a committed and determined army could defeat a wealthy and powerful nation.

The war also paved the way for China’s rise as a global superpower, as it took advantage of the conflict’s instability to expand its influence in Vietnam.

The Vietnam War was a long, bloody war and one of the most talked about in American history. 

The trauma and pain from the defeat remain fresh in the minds of Americans, especially veterans, while Vietnam is still struggling to recover fully from the conflict.

Though it was fundamentally due to ideological differences, it changed how the Western world views political conflict.
