Newly available evidence has shed new light on the inner workings of the socialist state in the Democratic Republic of Vietnam. In a “campaign against modern revisionism” in 1964 the militant faction within the Vietnamese Workers’ Party led by Lê Duẩn sidelined those members who favored a more cautious approach to the struggle for the reunification of the country. After the outbreak of the war, the propaganda machine in the DRV including writers and other artists had to foster popular support for the war and keep morale among civilians and soldiers high. The DRV Ministry of Public Security enforced ideological conformity and after 1965 intensified its efforts to track down and eliminate any party members and individuals who dissented from the aggressive line of the party leadership. Thus, in 1967, in the wake of the Tet Offensive the security apparatus lashed out against those who did not fully support Lê Duẩn’s risky plan for a general offensive and were not deemed fully reliable. The fact that many of those arrested or put under house arrest were close to General Võ Nguyên Giáp shows that the “Antiparty Revisionist Affair,” as the purge came to be known, was also part of internal factional infighting in Hanoi.
