Truman administration decided to provide substantial aid, loans and military assistance to Yugoslavia despite of some concerns caused by earlier relations.[3] Tito received US backing in Yugoslavia's successful 1949 bid for a seat on the United Nations Security Council, against Soviet opposition. In 1949, the United States provided loans to Yugoslavia, and in 1950 the loans were increased and followed by large grants and military aid. Even though the Yugoslavs initially avoided asking for military aid believing that it would be a pretext for a Soviet invasion, by 1951 Yugoslav authorities became convinced that Soviet attack was inevitable and Yugoslavia was included in the Mutual Defense Assistance program.
