The Tet Offensive the turning point in the Vietnam War

Marxist Theory · 2026-05-13

Core Argument

The central thesis is that the Tet Offensive of January-February 1968 was the decisive turning point in the Vietnam War not because it achieved military victory — indeed, the National Liberation Front suffered catastrophic casualties and failed to spark the anticipated general uprising — but because it shattered the political credibility of US imperialism at home and abroad. The article argues that the offensive exposed the gap between official propaganda and battlefield reality, fatally undermining domestic support for the war among the American working class and precipitating a crisis of morale within the US military itself. This political defeat, rather than any conventional military reversal, forced Washington onto a path of retreat that culminated in the humiliating fall of Saigon in 1975.

The article further contends that the Vietnamese victory was ultimately secured by the revolutionary dynamic within the United States: the anti-war movement, the radicalisation of working-class soldiers, and the breakdown of discipline within the US armed forces created conditions that made continued imperialist intervention untenable. The piece draws explicit parallels to the Iraq War, arguing that the same pattern of overconfidence, strategic miscalculation, and domestic opposition will produce the same outcome.

Theoretical Grounding

The analysis is rooted in the classical Marxist understanding of war as an extension of politics by other means, drawing on Clausewitz via Lenin. It treats the Vietnam War not as a discrete military conflict but as an expression of the contradictions of US imperialism in the post-1945 period: the drive to dominate Asia, the containment of revolutionary nationalism, and the competition between rival Stalinist bureaucracies in Moscow and Beijing.

The article deploys a materialist analysis of class forces within both Vietnam and the United States. It emphasises that the burden of the war fell disproportionately on working-class and black American soldiers, and that the anti-war movement's eventual success depended on its penetration of this layer. The concept of "morale" is treated not as a psychological abstraction but as a social phenomenon rooted in the class composition of the army and the relationship between the military and civil society.

The piece situates itself within the Trotskyist tradition's critique of Stalinism, arguing that the North Vietnamese regime, while progressive in its anti-imperialist struggle, was a "totalitarian bureaucratic caricature" modelled on Stalinist Russia. This is not treated as a contradiction to the support for Vietnamese national liberation but as a necessary political distinction: the working class must defend the Vietnamese revolution against imperialism while recognising that it did not establish workers' democracy.

Conjunctural Relevance

The article was written in 2008, on the 40th anniversary of Tet, and updated in 2025 for the 50th anniversary of the fall of Saigon. Its conjunctural relevance operates on two levels.

First, the piece draws explicit and sustained parallels between Vietnam and the Iraq War, which was ongoing at the time of original publication. It argues that the same dynamics are at work: imperialist overconfidence, the failure of "shock and awe" to break popular resistance, the impossibility of distinguishing combatants from civilians, the radicalisation of domestic opinion, and the eventual disintegration of military morale. The article cites the "surge" strategy in Iraq as a repetition of Nixon's "Vietnamisation" policy, and predicts a similar outcome.

Second, the 2025 postscript notes that Vietnam now faces the threat of capitalist restoration, with US imperialism potentially achieving through trade and investment what it failed to achieve through war. The United States has become Vietnam's largest trading partner; American credit card logos appear on victory parade floats; and the chemical companies that supplied Agent Orange now operate branches in Ho Chi Minh City. This observation connects the article to the contemporary conjuncture of neoliberal globalisation and the restoration of capitalism in formerly Stalinist states.

Where the Argument Continues

The article is part of a broader corpus of Marxist analysis on imperialism and war published by In Defence of Marxism. Several lines of argument are left open or underdeveloped:

  1. The nature of the North Vietnamese state: The article describes it as Stalinist but does not elaborate on the class character of the bureaucracy or the dynamics of its relationship with Moscow and Beijing. This is treated more fully in other IDOM articles on Stalinism and the degeneration of the Soviet Union.

  2. The post-war trajectory of Vietnam: The article notes the danger of capitalist restoration but does not analyse the internal class struggle within Vietnam since 1975. This connects to broader Marxist debates about the nature of "market socialism" and the transition to capitalism in China and Vietnam.

  3. The theory of guerrilla warfare: The article draws on Mao's "fish in water" analogy but does not engage with the broader Marxist literature on revolutionary warfare, including the debates between Mao, Giap, and Che Guevara.

  4. The anti-war movement's class composition: The article notes that working-class Americans turned against the war later than students but more decisively. This observation could be developed into a more systematic analysis of the relationship between the anti-war movement and the labour movement.

Relevant IDOM articles and Against the Stream episodes would include those on the Iraq War, the nature of Stalinism, the theory of permanent revolution, and the dynamics of US imperialism in the 21st century.

Key Quotes

  1. "The Tet offensive showed a considerable degree of military preparedness, skill and bravery on the part of the Vietnamese. It shook the morale of the US army, which was forcibly made aware of its own vulnerability, and it had a profound effect on US public opinion. However, from a military point of view it must be seen as a defeat for the NLF."

  2. "It is one thing to fight and die for a just cause, which earns the praise and admiration of the folks back home. It is another thing entirely to risk your life and suffer daily dangers and hardships for a cause in which you no longer believe and which your fellow citizens detest."

  3. "The 'strategy' outlined above in the words of Mr. Clifford ('to stay with it and ultimately hoping that the enemy would finally give up.') is the military equivalent of the philosophy of that incorrigible bankrupt Mr. Micawber, who was always 'confidently expecting that something will turn up.' This is very bad economics and even worse military doctrine."

  4. "The United States has now become Vietnam's single-largest trading partner. US imperialism may yet achieve through trade and investment what it failed to achieve with bombs and napalm."

  5. "The growing opposition to the war among the American working class was the result of hard experience. Kids from poor working class homes were the overwhelming majority of those drafted to fight in Vietnam. They were the ones most likely to be killed and maimed. As in Iraq, a disproportionate number were black or Latino."

  6. "Between 1969 and 1973, there was an increased incidence of fragging... The U.S. Army does not have any exact statistics on how many officers were killed in this manner. But they do know of at least 600 cases of confirmed fragging and another 1400 where officers died under suspicious circumstances. As a result of this, the U.S. Army was not at war with the enemy in the beginning of 1970. They were at war with themselves."
