1. Vietnamization of the War
Context:
In 1968, during the Tet Offensive, the massive attack by the Vietnamese forces shattered the "Limited War" strategy. This event shocked both the United States and the world, forcing the U.S. to develop a new strategy to salvage the situation. In 1969, President Nixon came to power and introduced the "Realistic Deterrence" strategy, continuing the colonial-style invasion and implementing the "Vietnamization of the War". This strategy expanded the conflict throughout Indochina, called the "Indochinaization of the War".
Intent:
The strategy aimed to "use the Vietnamese to fight the Vietnamese" and "use Indochinese to fight Indochinese".
Tactics:
Period 1969-1972:
- Gradually withdrawing U.S. and allied forces from the conflict
- Increasing the strength of the Saigon puppet army to "replace skin on the dead bodies"
- Expanding the war into Laos and Cambodia with the goal of using Indochinese forces against each other.
- Engaging in diplomatic deceit by exploiting Sino-Soviet tensions. Reaching agreements with China and easing relations with the Soviet Union to limit their support for the Vietnamese resistance.
- Implementing U.S. bombing campaigns against North Vietnam.
Post-Paris Accords, 1975:
- Although the U.S. withdrew from the battlefield, it kept 20,000 advisors and continued to aid the South Vietnamese army to prolong the war and sabotage the Paris Accords.
- Conducting operations like "Operation Rolling Thunder" and launching several military offensives in the liberated regions of Vietnam.
- Comparing the U.S. military strategies in Vietnam.

2. Unilateral Warfare
Context:
On November 7, 1954, the United States sent General Collin to serve as ambassador in South Vietnam with the aim of turning the region into a "neo-colony." This would serve as a launchpad for attacking the North and preventing the spread of revolutionary movements across Southeast Asia.
Using American support, Ngo Dinh Diem quickly established a dictatorial government in the South and worked to undermine the revolution. In mid-1954, Diem founded the "Labor Party" to establish a one-party system, and by the end of the year, he set up the "National Revolutionary Movement" with the goal of "fighting communism, colonialism, and feudalism."
Intent:
Unilateral Warfare was one of the U.S. military strategies in Vietnam, aimed at turning the South into a neo-colony. The purpose was to create a base for attacking the North and to block the rise of socialist movements across Southeast Asia.
Tactics:
Diem issued decrees to "outlaw communism" and, in May 1959, passed Law 10/59, which authorized mass executions across the South. The Diem regime also launched a land reform program to reclaim land previously given to the people by the revolution and established resettlement areas and strategic hamlets to control the population.

3. Special Warfare
Context:
At the end of 1960, following the "Dong Khoi" movement in the South, the United States devised and implemented one of its military strategies in Vietnam: the "Special Warfare" strategy in South Vietnam. At that time, nationalist liberation movements were growing globally, threatening the colonial systems of imperialism.
Intent:
This was a form of neo-colonial aggression, executed through proxy armies under U.S. command. With U.S. weapons and military technology, the strategy aimed to suppress the revolutionary movement of the Vietnamese people.
Tactics:
- Plan to pacify South Vietnam within 18 months.
- Increase military aid to Ngo Dinh Diem, boost American advisors and South Vietnamese forces.
- Force people into strategic hamlets, employing tactics like "helicopter assault" and "armored vehicle transports."
- Establish a U.S. military command in South Vietnam.
- Launch a series of sweeps to eliminate revolutionary forces and sabotage North Vietnam, blocking supply routes and naval access to prevent aid from reaching the South.

4. Limited Warfare
Context:
After the failure of the "Special Warfare" strategy, the U.S. shifted to a new approach, the "Limited Warfare" strategy, in South Vietnam. This strategy was introduced to salvage the situation in the South, and it spanned from 1965 to 1968.
Intent:
"Limited Warfare" was a form of neo-colonial aggression executed by U.S. troops, allied forces, and South Vietnamese soldiers. Its purpose was to gain a military advantage and restore control on the battlefield.
Thanks to this strategy, the U.S. quickly outnumbered and outgunned Vietnamese forces, hoping to regain the upper hand and push the enemy into a defensive position, forcing them to retreat and deplete their resources.
Tactics:
- Constantly send in U.S. expeditionary forces and modern military equipment, with the number of U.S. troops in the South exceeding 500,000 by 1968.
- Carry out two major dry season counteroffensives (1965-1966 and 1966-1967), using numerous operations to "search and destroy" and pacify "Viet Cong strongholds."
- Destroy the economic and military infrastructure in the North to prevent external support, thereby weakening the resolve of the Vietnamese people in the South.
