Examine the historical significance of the Tet Offensive in 1968 that shaped the developments of the Second Indochina War [Video by History]

Historical Context: Ho Chi Minh’s Plan
On 30-31 January 1968, the North Vietnamese forces and the Viet Cong launched a coordinated military campaign in South Vietnam. It coincided with the Vietnamese New Year, known as the Tet, in which many South Vietnamese soldiers were preoccupied with this celebration.

Ho Chi Minh formulated this plan to carry out the Tet Offensive to achieve two main goals:

  • To sow discord between the United States and South Vietnamese forces.
  • To cause an internal collapse of authority within South Vietnam and spark unrest to oppose the Saigon regime.

During the Battle of Hue, the Viet Cong overran the city and took control of Hue, claiming the lives of thousands of inhabitants within. The Allied troops had to take nearly a month to regain control of Hue. In doing so, the USA had incurred rising casualties, which was a problem concealed by the government.

The Viet Cong fighters piled into a truck and a taxicab and drove to their target. Just before 3 A.M., as they drove past the night gate, the Viet Cong opened fire on the two American guards stationed there. […] Shortly after 9 A.M., the embassy was officially declared clear of all enemy fighters. General William Westmoreland, commander of all U.S. forces in Vietnam, strode onto the embassy grounds in clean, pressed uniform. Westmoreland told reporters that the attack on the embassy had been part of a wider Viet Cong assault across Vietnam. He complained that the Viet Cong had broken a holiday truce to stage these attacks.

An excerpt taken from “The Tet Offensive: Turning Point of the Vietnam War” by Dale Anderson.

Although the campaign targeted more than 100 cities and towns, including the southern capital Saigon, it was a catastrophic military disaster for the communists. As many as 50,000 communist troops died in their attempt to gain control of South Vietnam.

Unintended Consequences: The Quagmire
Nonetheless, the repercussions of the Tet Offensive on the United States were serious. As the Johnson administration had repeatedly reassured the American public that a swift and decisive victory was possible in Vietnam, the Tet Offensive had raised doubts on this promise.

The American journalist Walter Cronkite had exposed the deception of the Johnson administration in a provoking broadcast. This revelation was made after his personal trip to Hue in Vietnam, in which the most intense urban warfare took place during the war.

We have been too often disappointed by the optimism of the American leaders, both in Vietnam and Washington, to have faith any longer in the silver linings they find in the darkest clouds. […]

To say that we are closer to victory today is to believe, in the face of the evidence, the optimists who have been wrong in the past. To suggest we are on the edge of defeat is to yield to unreasonable pessimism. To say that we are mired in stalemate seems the only realistic, yet unsatisfactory, conclusion. On the off chance that military and political analysts are right, in the next few months we must test the enemy’s intentions, in case this is indeed his last big gasp before negotiations. But it is increasingly clear to this reporter that the only rational way out then will be to negotiate, not as victors, but as an honorable people who lived up to their pledge to defend democracy, and did the best they could.

An excerpt taken from Walter Cronkite’s “We are mired in stalemate” broadcast, 27 February 1968.

As a result, public sentiments became to shift in favour of US withdrawal from Vietnam, given that the people realised that a victory in Vietnam was unlikely, as outlined by Cronkite’s broadcast. Faced with mounting popular pressure, Johnson announced on 31 March 1968 that he would not seek a second term as president of the United States. His successor, Richard Nixon, then proceed with the policy of “Vietnamisation“, which led to a new phase of the US role in the Second Indochina War.

JC History Tuition Singapore - What is the relationship between Vietnam and the ASEAN countries

What is the relationship between Vietnam and the ASEAN countries?

The Cold War lens: Consequences of the Second Indochina War
During the Vietnam War, the Paris Peace Accords were signed on 27 January 1973, which provided an official basis for the full withdrawal of the American troops from South Vietnam. As part of the 1969 Nixon Doctrine, the reduced commitment of the USA in the Asia-Pacific meant that there was a corresponding decline in its military presence in Thailand and the Philippines.

However, Hanoi held deep suspicions of the US motives of manipulating ASEAN as a Cold War instrument in the region, which conflicted with ASEAN’s neutral position as declared under its 1971 Zone of Peace, Freedom and Neutrality (ZOPFAN). Even after the Paris Agreement, some ASEAN member nations maintained relations with the Provisional Revolutionary Government of the Republic of South Vietnam (PRG), which Hanoi interpreted as a confirmation of its suspicions.

Besides, tensions were high as Thailand turned to China for help with its looming border security threat. In February 1979, Vietnam and China clashed in a short military confrontation, which could be seen as an extension of the Sino-Soviet split.

In Hanoi’s view, ASEAN is both an offshoot and a disguise of the US-led SEATO that serve the US interests and this explained the “insincerity of ASEAN proposal of neutrality”. Thus, in Hanoi’s future relations with ASEAN the opposition aspect would be greater than the cooperation aspect. Moreover, cooperation should serve to drive a wedge among ASEAN member states, that is “to exploit contradictions among those in the opposite side”, which had become one of the guiding principles of the Vietnamese foreign policy with respect to ASEAN.

An excerpt taken from “Flying Blind: Vietnam’s Decision to Join ASEAN” by Nguyen Vu Tung.

After the fall of Saigon, Deputy Foreign Minister Phan Hien raised a ‘four-point position’ in July 1976, which antagonised ASEAN nations. For instance, one of the four points stated “Regional states should develop cooperation among themselves in accordance with the specific conditions of each state and in the interest of genuine independence, peace, and neutrality in Southeast Asia, thus contributing to the cause of world peace.”

At this stage, Vietnam refused to recognise ZOPFAN and join ASEAN.

Mounting Tensions: The Third Indochina War
In December 1978, Vietnamese troops invaded Kampuchea, causing the outbreak of the Third Indochina War that alarmed ASEAN. On 7 January 1979, a pro-Vietnamese government known as the People’s Republic of Kampuchea (PRK) was formed. As a result, ASEAN-Vietnam relations soured.

In response to this gross violation of national sovereignty, ASEAN made repeated joint statements to call for the immediate withdrawal of foreign troops from Kampuchea and the recognition of self-determination. In particular, ASEAN took the lead in calling for the formation of the Coalition Government of Democratic Kampuchea (CGDK) that comprised of three anti-Phnom Penh factions in June 1982.

The Vietnam Ministry of Foreign Affairs (MOFA) retaliated by declaring ASEAN countries as “hostile to Vietnam” from 1979 onwards.

As far as ASEAN is concerned, Vietnam is pursuing tactics that deliberately evade and obscure the central fact of the issue: Vietnamese armed occupation of Kampuchea. ASEAN rejects that implicit bilateralization of the problem in Vietnam’s effort to define it as a Thai-Kampuchean border dispute. Moreover, ASEAN has been unwilling to see the Vietnamese military presence in Kampuchea be submerged in a diffuse general agenda on problems of peace and stability in Southeast Asia that might include such topics as US basis in the Philippines. […] Furthermore, Vietnamese initiated bilateral official contacts with ASEAN states appear to be manipulated in a manner calculated to crack ASEAN’s external solidarity by driving a political wedge between the members.

An excerpt taken from “Southeast Asia Divided: The Asean-Indochina Crisis” by Donald E. Weatherbee.

A new age: Post-Cold War transition
On 23 October 1991, the Paris Peace Agreements were signed, marking an official end of the Third Indochina War. The late 1980s marked a turning point for ASEAN-Vietnam relations. Vietnam launched its Doi Moi reform policy to undergo political and economic transformation in both domestic and international fronts. In terms of foreign policy, Vietnam sought to strengthen diplomatic relations with ASEAN member nations in spite of its past transgressions.

The period 1992-1995, spanning an interview from the collapse of the Soviet Union and normalization of relations with China through full membership in ASEAN and diplomatic recognition by the United States, was also a time of significant change in elite views of the nature of the international system, and its implications for Vietnam.

[…] The abrupt end of the Cold War and the collapse of Vietnam’s main supporter certainly qualifies as a major “external shock”, and it had been preceded by the economic shock of the 1980s which, by undermining the old ways of conceiving socialism, had cleared the way for new thinking in the external sphere.

An excerpt taken from “Changing Worlds: Vietnam’s Transition from Cold War to Globalization” by David W. P. Elliott.

In 1992, Vietnam joined the Treaty of Amity and Cooperation (TAC). On 28 July 1995, Vietnam joined ASEAN as a full member. Subsequently, Vietnam participated in the ASEAN Free Trade (AFTA), facilitating regional economic integration that made ASEAN flourish economically.
