The Vietnamese communist leadership displayed a remarkable degree of ingenuity and resourcefulness in its quest to drive out the Americans, finish off the regime in Saigon, and win the conflict by achieving national reunification under its exclusive aegis. At times, it proved callous to the extreme, making choices it understood might result in massive death and suffering for its people. Increasingly reliant over time upon military and other aid from socialist allies, most notably China and the Soviet Union, it still jealously guarded its autonomy, refusing even to consult those allies about major strategic matters. The audacity and temerity of the Hanoi Politburo were matched only by its impenetrability and staunchness. In the end, it prevailed over its enemies owing less to their shortcomings than to the merits of its masterfully crafted and carefully calibrated strategy of “struggle” on three separate yet closely intertwined fronts.

Hanoi entered into negotiations with Washington and Saigon in 1968–9, Chapter 4 explains, but merely to probe and sow division among its enemies. But then unsettling circumstances intervened, including the Sino-Soviet Border War of early 1969; the death a few months later of Ho Chi Minh, who, despite his lack of influence over communist decision-making, remained the venerable face of the Vietnamese struggle for reunification and independence and thus an important public relations tool; and, finally, Nixon’s decisions to “Vietnamize” the anticommunist war effort in the South and then to authorize incursions into Cambodia and Laos. The period 1969–71 was marked by uncertainty and indecisiveness as communist decision-makers reassessed their strategic priorities and placed greater emphasis on alternative modes of struggle. Concerned about potential diplomatic isolation and the loss of Soviet and Chinese support, Le Duan decided to go-for-broke once more. The 1972 Easter Offensive was an abject disaster. Hanoi then tried its luck at the bargaining table, resulting in the Paris peace agreement of 1973 and the suspension of the Fourth Civil War for Vietnam.

Chapter 4 relates the impact of the Americanization of the Fourth Civil War for Vietnam. Despite public claims to the contrary, Hanoi at that time had no desire to negotiate an end to the conflict; it was committed to “complete victory.” Nothing short of the surrender of its enemies was going to satisfy it. To meet that end, Le Duan’s regime relied heavily on political and material support from the Soviet Union and China, which was not always easy to obtain in light of the growing ideological dispute between the two. Mounting frustration with the course of the war eventually prompted Le Duan to order a major, months-long military campaign to break the stalemate and expedite victory: the Tet Offensive of 1968. Although it dealt the United States a major psychological blow, the three-staged offensive fell far short of meeting Le Duan’s own expectations. In fact, it energized the regime in Saigon and rallied the Southern population behind it to an unprecedented degree.

The “two-camp theory” prompted Vietnamese communists to instigate a civil war – the Fourth Civil War for Vietnam – to neutralize domestic rivals immediately after World War II ended. When France initiated its recolonization of Vietnam and the rest of Indochina in fall 1945, Chapter 2 relates, many Vietnamese noncommunist nationalists and other victims of communist attacks and repression opted to collaborate with its armies, for the time being. Thus, the French war in Vietnam became entwined with the Vietnamese Civil War; it also significantly augmented national fracturing and fratricidal violence. French manipulation, a misreading of Vietnamese political realities, and the intensifying state of the Cold War prompted the United States to intrude. By the time of the climactic Battle of Dien Bien Phu, in spring 1954, the United States was footing nearly 80 percent of the French war bill, and Washington policymakers had become obsessed with the evolving situation across the Indochinese Peninsula. The Geneva accords of July 1954 concluded the French War and paused the Vietnamese Civil War by creating two Vietnams separated at the Seventeenth Parallel.

The United States pulled out the last of its combat troops from South Vietnam in March 1973. That ended the American War and completed the de-Americanization of the Fourth Civil War for Vietnam. Shortly after the signing of the Paris agreement, Hanoi resumed combat operations. The regime in Saigon, communist decision-makers publicly claimed, had failed to honor its side of the bargain, leaving them no choice. In 1974–5, Le Duan’s regime mounted yet another major campaign to bring about the collapse of its counterpart in the South. This time it calculated correctly, and its armies triumphed. Chapter 6 relates the rationale for Hanoi’s decision to proceed with the campaign, despite the possible resumption of US attacks against the North, and the reasons for its ultimate – and final – triumph on 30 April 1975.

Chapter 3 explains that Ho Chi Minh insisted on respecting the basic terms of the Geneva accords even as it became obvious that the rival regime headed by Ngo Dinh Diem in Saigon had no intention of doing the same. Ho’s passivity in the face of Diem’s actions shocked and dismayed some of his own followers, especially in the South. In 1959, Hanoi finally sanctioned insurgent activity below the Seventeenth Parallel, but under restricting guidelines because Ho feared provoking US intervention. His tentativeness alienated growing segments of partisans, including Le Duan, a rising star in the communist ranks. By 1963, the tension between Ho and other “doves,” on the one hand, and Le Duan and other “hawks,” who favored all-out war to “liberate” the South, on the other, had split the Vietnamese communist movement into two competing, rival wings. Following Diem’s overthrow in a coup abetted by the United States in early November 1963, Le Duan and his chief lieutenants staged a coup of their own in Hanoi. The new regime at once escalated hostilities in the South, resuming the Fourth Civil War for Vietnam and setting Hanoi on an irreversible collision course with the United States.

The epilogue explains that the resilience and stubbornness of Le Duan and other communist leaders hindered the country’s reconstruction and development after the Vietnamese Civil War finally ended. In the decade of life and leadership left for Le Duan, few positive changes took place in Vietnam. The 1978–9 incursion into Cambodia eliminated the Khmer Rouge threat, but the decade-long occupation of that country by Vietnamese forces that followed brought worldwide condemnation. Vietnam contained the Chinese incursion into its own territory in 1979, but anti-Chinese campaigns domestically prompted an exodus of tens of thousands of productive members of society. Through all this, Le Duan’s unwavering adherence to Stalinist principles of economic transformation hampered economic growth. His death in 1986 paved the way for Đổi mới, the “renovation” policy that introduced market reforms. It also set the stage for the normalization of diplomatic relations with the United States – and of life itself for average Vietnamese. Although Vietnam’s American War and Fourth Civil War have been over for nearly fifty years, the struggle for their memory continues.
