A Dissertation About the Vietnam War and Soviet Military Aid

Scholarly debate surrounding the history of the Vietnam War includes several key issues. A central approach to writing its history by orthodox historians not long after the end of the war was that, it was unnecessary to fight and the policies that led to it were foolhardy.¹ These writers were followed by revisionists who wrote about the war differently emphasizing that it was a good cause that failed to contain communism, but it was defeated by civil unrest and political conflict at home.² Post-revisionism focused upon the actions of the Vietnamese doing the fighting, and it wrote about the complications and unexpectedness involved in the war.³ Recently, writers have taken the approach of examining the war from Vietnamese and global perspectives.⁴

This dissertation focuses upon how Soviet military aid influenced North Vietnamese strategy. It employs the use of archival evidence that is predominantly contained within recently declassified documents in American scholarly databases and research institutions. Most archives from Vietnam in Ho Chi Minh City, and Hanoi are limited since the current regime has not made sources from the Vietnam War publicly available (e.g., the Party, the Military, the Foreign Ministry).⁵ Some writers gained access to good sources at the Ministry of the Interior in Vietnam. This dissertation makes good use of archival evidence involving Soviet military aid that are in United States repositories.

The topic of this dissertation fits into the recent historiographical efforts to explain the war from the vantage point that America was defeated by North Vietnam. It encompasses the strategy that secured victory for the North and its allies. Research on Soviet military aid yields evidence that the Soviets increased their aid after the Americans undertook Operation Rolling Thunder in 1965.⁶ The U.S. also attacked Hanoi in 1972 during Operation Linebacker II. Hanoi was heavily defended by Soviet provided antiaircraft missiles (SA-2s) or SAMs, and the North Vietnamese employed the use of Soviet advisers and radar systems. Many American B-52s were used during these bombing campaigns of North Vietnam, and these bombers were often defended by fighter jets to protect them. Some jets would precede the bombers, fly the same course and, try and eliminate the North Vietnamese antiaircraft installations before the B-52s arrived.⁷ The defense of Hanoi was a central strategic victory for the North (forced the U.S. to the negotiation table after Linebacker II) even though in many wars the strategic value of the capital city is not necessarily so essential that its loss leads to defeat. General George Washington lost the battle of Brandywine, which determined control of Philadelphia, to the British. However, he did not make a strong effort to defend the city, as he believed other areas held greater strategic value.

North Vietnam made intense efforts to keep authority within their own sphere, and they did not want to fight the war how China or the Soviets wanted them to. They knew accepting Soviet aid would lead to the Soviets pressuring them to enter a ceasefire with the U.S. The North Vietnamese communist regime made many strategic decisions independently, including key attacks on the South (e.g., Tet Offensive, Easter Offensive). These actions ultimately enabled them to unite all of Vietnam under communism after Southern forces collapsed roughly two years following the American withdrawal under the 1973 ceasefire agreement. Did Soviet aid play a key factor in the capitulation of the South, or did it have no appreciable effect? One way to analyze this is to examine when the Soviet aid shipments were cut back and if this led to greater American or South Vietnamese military victories.⁹

The defense of Hanoi from American strategic bombers could not have been effectuated without Soviet military equipment. Many historians believe the U.S. bombing attacks on Hanoi failed or the objective was unmet. This dissertation expounds upon that idea and further examines not only how Soviet aid enabled the North to sustain its war effort successfully, but also how that aid was a central factor in the United States’ eventual defeat in the war.
