After the British government declared on 21 February 1947 its inability to provide financial aid (though she would establish the Central Treaty Organization a decade later), Turkey turned towards the United States, who drew up the Truman Doctrine, pledging to "support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures". $100 million was appropriated two months after the US Congress ratified the Truman Doctrine on 12 March 1947. This figure was raised to $233 million by 1950, after Turkey contributed a brigade of about 5000 men to the United Nations forces in the Korean War. In August 1947, the Joint American Military Mission for Aid to Turkey (JAMMAT) was established in Ankara under the authority of the US ambassador.
