Despite its strong appeal, communist ideology alone could not determine where communist movement would succeed in seizing power. Other large movements in Indonesia and the Philippines, for instance, were unable to gain ascendency. The Indonesian communist movement was brutally crushed and eliminated after the Indonesia armed forces seized power in 1965. In the Philippines, President Marcos declared martial law and imposed authoritarian rule partly to counter the rising threat of the New People’s Army (NPA), the armed wing of the communist movement. Marcos failed to crush the NPA. Successive governments were also unable to do so, although the NPA never obtained sufficient support to overthrow either Marcos or democratic governments that succeeded him.
