Lon Non

Non was the younger brother of Prime Minister (and later President) Lon Nol. As a result, he was often referred to as "Little Brother" (French: Petit frère) in political circles, in which he was regarded as a somewhat Machiavellian figure who was determined to protect his brother's monopoly on power. Non was executed by members of the Khmer Rouge after the Communist seizure of Phnom Penh in April 1975.

Despite a period in America as the Republic's "Ambassador-at-Large", General Lon Non returned to Cambodia during 1974 and resumed his political activities: John Gunther Dean, the US ambassador, soon complained about Non's "frantic maneuvering", and appealed for US government assistance in controlling him. He appears to have been responsible for a bizarre last-ditch plot in which a group of students, led by a man named Hem Keth Dara and posing as a faction of the Khmer Rouge (under the title of Monatio, or the 'National Movement') attempted to seize key parts of the city ahead of the actual Communist forces. Along with Long Boret he made efforts to broker a cease-fire agreement, despite both having been threatened with execution by the Khmer Rouge. Non remained in the city until it fell to the Khmer Rouge on April 17, and was detained by their forces at the Information Ministry. He was seen along with a group of officials under guard, looking apparently composed, "impeccably dressed" with a freshly starched uniform and trimmed moustache, and smoking a pipe. It is possible that he may have believed that the arrest was being carried out largely for 'effect', and that the Communists wished to work with him in the future.

The American government, the main supplier of aid to the Republic, began applying increasing pressure on Lon Nol to reduce his brother's influence, concerned about the latter's corruption, lack of moral scruple (combined with unusual ambition and energy) and his suspected implication in bombing and other attacks on his political rivals. Australian intelligence confirmed that Non had formed an assassination unit, called the "Republican Security Battalion", which used a fleet of yellow Hondas. The US suggested a variety of posts to occupy Lon Non's energies, or induce him to get out of the country: in 1973, after Non was eventually forced to leave Cambodia, his wife was caught with $170,000 in US$100 bills at Orly Airport in Paris as she was leaving to join her husband in the United States.

By early 1972 Lon Non finally managed to drive Sirik Matak from the government after organising groups of students to demonstrate against him. When, later in 1972, presidential elections were held, Non boasted that the monolithic vote of the Khmer National Armed Forces had secured his brother's inevitable victory. Non, who was ultimately to become Minister of the Interior, also created the Sangkum Sathéaranak Râth (the Socio-Republican Party, PSR) as a political organisation to represent the interests of Lon Nol and the officer corps. The two rival parties, In Tam's Democratic Party and Sirik Matak's Republicans, refused to contest the elections to the National Assembly in September 1972, leading to the PSR's total dominance.

Under the administration of Prince Norodom Sihanouk, Non served as an officer of the military police, reaching the rank of Major. Subsequent to the Cambodian coup of 1970, in which Sihanouk was ousted by Lon Nol, then serving as Prime Minister, Non was rapidly promoted. Despite a lack of substantial military experience, he was soon given the rank of Colonel, and then General: the 'elite', American-trained militias of the Khmer Kampuchea Krom and Khmer Serei, flown into the country after the coup, were placed under his command. The massacres of Vietnamese residents of Cambodia in the period subsequent to the coup are thought to have been carried out by the military under Lon Non's direction.

Non's political motivation seems to have partly derived from an unswerving loyalty to his brother, and his machinations against the coup's other main figure, Prince Sisowath Sirik Matak, caused serious divisions in the Cambodian administration. While Lon Nol was in poor health during 1970 and 1971, his brother and the army made it clear they would accept no other leader and made efforts to sideline Sirik Matak, who was given the title of "Prime Minister-Delegate". In 1971 Non raised his political profile by directing a moderately successful military operation, Akineth Moha Padevuth, driving Communist guerrillas from villages around National Route 3 (Akineth was a wizard and hermit in the Reamker on whom Non seems to have modelled himself).

Lon Non (Khmer: លន់ ណុន; 18 April 1930(?) – 17 April 1975) was a Cambodian politician and soldier who rose to his greatest prominence during the Khmer Republic (1970–1975).
