In the early years the party became known for its parliamentary and extra-parliamentary opposition against the rising Cold War, and especially the placement of nuclear weapons. The socialist revolution in Cuba and uprisings against the South African system of Apartheid led to considerable debate within the party between groups who opposed all violence and groups who opposed repressive violence (from the ruling class) and supported liberating violence (against the ruling class). In 1961 the party threw off its principled pacifism and advocated the minimization of violence. Extra-parliamentary action against colonialism also became more important; the party supported New Guinean and Algerian independence.
