People's war (Chinese: 人民战争), also called protracted people's war, is a Maoist military strategy. First developed by the Chinese communist revolutionary leader Mao Zedong (1893–1976), the basic concept behind people's war is to maintain the support of the population and draw the enemy deep into the countryside (stretching their supply lines) where the population will bleed them dry through a mix of mobile warfare and guerrilla warfare. It was used by the Chinese communists against the Imperial Japanese Army in World War II, and by the Chinese Soviet Republic in the Chinese Civil War. The term is used by Maoists for their strategy of long-term armed revolutionary struggle. After the Sino-Vietnamese War in 1979, Deng Xiaoping abandoned people's war for "People's War under Modern Conditions", which moved away from reliance on troops over technology. With the adoption of "socialism with Chinese characteristics", economic reforms fueled military and technological investment. Troop numbers were also reduced and professionalisation encouraged. The strategy of people's war was used heavily by the Viet Cong in the Vietnam War. However, protracted war should not be confused with the "foco" theory employed by Che Guevara and Fidel Castro in the Cuban Revolution of 1959. In its original formulation by Chairman Mao Zedong, people's war exploits the few advantages that a small revolutionary movement has—broad-based popular support can be one of them—against a state's power with a large, professional, well-equipped and well-funded army. People's war strategically avoids decisive battles, since a tiny force of a few dozen soldiers would easily be routed in an all-out confrontation with the state. Instead, it favours a three-phase strategy of protracted warfare, with carefully chosen battles that can realistically be won. In phase one, the revolutionary force conducting people's war starts in a remote area with mountainous or forested terrain in which its enemy is weak. It attempts to establish a local stronghold known as a revolutionary base area.
