Phạm Ngọc Thảo
Phạm Ngọc Thảo (IPA: , ), also known as Albert Thảo (14 February 1922 – 17 July 1965), was a communist sleeper agent of the Việt Minh (and, later, of the People's Army of Vietnam (PAVN)) who infiltrated the Army of the Republic of Vietnam (ARVN) and also became a major provincial leader in South Vietnam. In 1962, he was made overseer of Ngô Đình Nhu's Strategic Hamlet Program in South Vietnam and deliberately forced it forward at an unsustainable speed, causing the production of poorly equipped and poorly defended villages and the growth of rural resentment toward the regime of President Ngô Đình Diệm, Nhu's elder brother. In light of the failed land reform efforts in North Vietnam, the Hanoi government welcomed Thao's efforts to undermine Diem.During the First Indochina War, Thảo was a communist officer in the Việt Minh and helped oversee various operations in the Mekong Delta in the far south, at one point commanding his future enemy Nguyễn Khánh, who briefly served the communist cause. After the French withdrawal and the partition of Vietnam, Thảo stayed in the south and made a show of renouncing communism. He became part of the military establishment in the anti-communist southern regime and quickly rose through the ranks. Nominally Catholic, Thảo befriended Diệm's elder brother, Archbishop Pierre Martin Ngô Đình Thục—the devoutly Roman Catholic Ngô family strongly favored co-religionists and had great trust in Thảo, unaware that he was still loyal to the communists. He went on to serve as the chief of Bến Tre Province, and gained fame after the area—traditionally a communist stronghold—suddenly became peaceful and prosperous. Vietnamese and US officials, as well as journalists hostile to or supportive of Saigon, misinterpreted this as a testament to Thảo's great ability, and he was promoted to a more powerful position where he could further his sabotage. Thảo and the communists in the local area had simply stopped fighting, so that the communists could quietly recuperate, while Thảo would appear to be very skillful and be given a more important job where he could do more damage.
Through intrigue, Thảo also helped destabilise and ultimately unseat two South Vietnamese regimes—Diem's and the military junta of Khánh. As the Diệm regime began to unravel in 1963, Thảo was one of the officers planning a coup. His plot was ultimately integrated into the successful plot and his activities promoted infighting which weakened the government and distracted the military from fighting the Viet Cong insurgency. Throughout 1964 and 1965, as South Vietnam was struggling to establish a stable state after the ouster of Diệm, Thảo was involved in several intrigues and coup plots which diverted the government from implementing its programs. In 1965, he went into hiding after a failed attempt to seize power from Khánh and was sentenced to death ''in absentia''. Although this coup also failed, the subsequent chaos forced Khánh's junta to collapse. Thảo died the same year he was forced into hiding; it is believed that he was murdered after a bounty was placed on his head.
Thảo's real identity as a sleeper agent was kept secret after the end of Vietnam War. One of the reasons was to protect Thảo's family, which at that time had members living in the United States. His secret identity was eventually revealed and the unified Socialist Republic of Vietnam posthumously awarded him the title Hero of the People's Armed Forces in 1995.
