From jacket flap:
Asia is a battlefield of Russian Communism and democratic ideals; she is split by revolutions inspired, directed, and supported by the USSR. Justice William O. Douglas, a man whose interest and insight have won for him the esteem of a great American audience, visited and studies five of these crucial fronts in Asia. This is the fascinating account of what he discovered – what is going on inside Malaya, the Philippines, Indo-China, Burma, and Formosa. It is a revealing record of Communist revolutionary tactics, and a brilliant exposition of the only strategy by which Asia can stem the tide of Communism: the counterrevolution.
The Communist revolutionaries in Malaya, Indo-China, and the Philippines receive arms and ideals from Moscow. They strike at key men and positions, and then disappear into the jungles or the rice paddies, never exposing themselves to a superior force. The man hunt is the only means of tracking them down – a costly means. Justice Douglas believes that the guerrillas will never be wiped out until the people rise against them.
