Why Did The US Lose The Vietnam War

Guerrilla War Techniques Against The US Army By The North Vietnam Soldiers

The Soldiers of North Vietnam already learned a lot about Guerrilla warfare techniques during the First Indochina War (1946-1954) against France.

The First Indochina War already uplifted them to experienced warriors.

In the Second Indochina War (or Vietnam War) locations, where the battles happened were quite easy to use Guerrilla warfare techniques.

North Vietnam soldiers took full advantage of the situation.

They created hundreds and thousands of tunnels under the war locations.

It was very difficult for America to find out these tunnels due to they were fully surrounded by dense jungles and rivers.

Even, they created tunnels in such huge numbers that it had the capability to hide all the soldiers of North Vietnam.

Their soldiers kept hiding until American troops arrived there. Whenever they saw American soldiers came into the jungles, they suddenly attacked and killed them.

This was one of the first biggest drawbacks of why America had to lose the battle.

If you want to know how was the war of Vietnam really looked like, you can watch this movie, name ‘We Were Soldiers’ (2002).

A Complete New War Environment For The US Soldiers

The 2nd biggest reason was the new war environment for US soldiers.

The US military fought many major battles for a long time. They did some great performances during the first and second World War periods.

But in Vietnam, the situation was completely different.

Because here, the battlegrounds were fully surrounded by dense Jungles and rivers.

The US troops were quite inexperienced in fighting such ground-level battles.

But at the same time, it was the good luck of North-Vietnam Soldiers that the war locations were fully surrounded by Jungles, bogs, and rivers.

It helped them so much.

Because if, the situation were different then perhaps they would not be able to stand in front of the modern warfare techniques of the Americans.

Guerrilla Warfare and this new unfavorable environment were the two main causes why more than 58,000 US soldiers lost their lives and more than 1.2 lakhs soldiers got heavily wounded.

It obligated the powerful United States to retreat their troops.


Internal Pressure In The US – Due To The Inability of Showing The Cause

North Vietnam was a Communist nation and they wanted to unite the whole country by capturing the power of the Southern part also.

(The South was fully supported by the United States)

For them, that was all their internal political matter.

But the US anyhow wanted to stop Communism’s expansion in Southeast Asia. Simply, they feared the Domino theory.

They feared that the rise of Communism in Vietnam would contribute to the fall of the Democratic governments in other South and Southeast Asian nations; mainly in India, Laos, Brunei, Sri Lanka, Pakistan, Myanmar, Nepal, Bhutan, etc.

Therefore, they didn’t want that to happen. This was all a matter of fact of the cold war era. The USA never wanted the Soviet Union to become more powerful.

But for the citizens of the United States, that couldn’t be an argument for their country to fight against Vietnam and let their soldiers die.

For US citizens, the war was unnecessary.

Especially, when they saw some brutal incidents like the Mai Lai Massacre, they started protesting against the US government’s decision.

Even, the US media left supporting the government.

Finally due to the pressure of protest, in 1973, President Richard Nixon obliged to withdraw American troops from Vietnam.

Many political analyzers also consider this incident a major failure of America’s foreign policy.


Support To North Vietnam From The Soviet Union And China

The main communist nations USSR and China also involved in the Vietnam War against the USA.

Actually, the small country became like a battleground for these large powers’ proxy war.

The Soviets and Chinese didn’t directly fight against US troops, but indirectly they created a lot of difficulties for Americans.

Especially, they kept supporting North Vietnam by providing funds, military training, weapons, and other necessary supplies.

It helped them a lot.

Soviet Russia and China always wanted the country to get unite and become a full communist nation like them.

These two major countries’ support also became a major blow to the defeat of the United States of America.


So, these were the four reasons why did the US lose the Vietnam War.

We hope this answer remained a little helpful to you.
