Siddhi Savetsila

On 8 May 2000, he was among the five Free Thai veterans who were awarded the Agency Seal Medallion by CIA director George Tenet.

In August 1990, the new Prime Minister Chatichai Choonhavan dismissed Siddhi as he sought a more pragmatic relationship with the communist-ruled countries of Southeast Asia. Siddhi's SAP was in great difficulties during the late 1980s and, in September 1990, Siddhi gave up his chairmanship. One month later, he completely retired from the parliament and the party, stating that he was tired of politics. In 1991 King Bhumibol appointed him to his privy council.

In 1980, Kriangsak appointed him minister of foreign affairs. He kept this position when Prem Tinsulanonda took over the premiership a few months later. As Thailand' representative in the United Nations (UN) and ASEAN, Siddhi advocated a tough line towards Vietnam which was occupying Cambodia after 1979. In 1983, Siddhi was elected member of parliament and in 1985 he took over the leadership of the Social Action Party (SAP) following the retirement of Kukrit Pramoj. The party did well in the 1986 election and Siddhi additionally became deputy prime minister for a short time.

He then served in the Royal Thai Air Force and rose up to the rank of air chief marshal (phon akat ek). From 1975 to 1980 he served as secretary-general of the National Security Council. In this position he assisted Prime Minister Kriangsak Chomanan at the time of the Vietnamese invasion of Cambodia 1978/79.

Siddhi studied metallurgic engineering at the Massachusetts Institute of Technology (MIT), graduating with an S.B. degree in 1943. During the Second World War, he joined the Free Thai Movement (Seri Thai) which resisted against the de facto occupation of Thailand by Japanese forces. He collected data for the US foreign-intelligence agency OSS (predecessor of the CIA) and was temporarily detained by the Japanese. Two of Siddhis sisters married US intelligence operatives, one was the wife of former OSS agent Willis Bird and one of CIA officer William Lair. After the end of the war, he returned to the MIT and received his S.M. degree in 1947.
