In 1958, the upswing in violence against the government of South Vietnam continued, much of which was committed by the communist-dominated insurgents now called the Viet Cong (VC). In South Vietnam, President Ngô Đình Diệm appeared to be firmly in power, although many American officials expressed concern about the repressive nature of his regime. The United States continued to finance most of the budget of the government of South Vietnam. North Vietnam continued to campaign for reunification with the South while focusing on its internal economic development, but pressure from hard-pressed communists in the South was forcing the North to contemplate a more active military role in overthrowing the Diệm government.
