Anatolia 's geostrategic value has long attracted players of the New Great Game . After the Yalta and Potsdam Conferences in 1945 , Joseph Stalin sent naval ships and troops to the region with his sights set on the Dardanelles . In 1946 , the Soviet Union sent two diplomatic notes concerning the Montreux Convention Regarding the Regime of the Turkish Straits , arguing that its terms were unfavorable to the Soviets . Ankara dismissed the notes , and the US also expressed its dissatisfaction with Soviet demands , stating that " Should the Straits become the object of attack or threat of attack by an aggressor , the resulting situation would constitute a threat to international security and would clearly be a matter for action on the party of the Security Council of the United Nations . " 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
