Eisenhower was convinced in 1946 that the Soviet Union did not want war and that friendly relations could be maintained; he strongly supported the new United Nations and favored its involvement in the control of atomic bombs. However, in formulating policies regarding the atomic bomb and relations with the Soviets, the administration of President Harry S. Truman largely ignored senior military leaders in favor of the State Department. By mid-1947, as East–West tensions over economic recovery in Germany and the Greek Civil War escalated, Eisenhower had come to agree with the containment policy of stopping Soviet expansion. Increasingly frustrated with his position of chief of staff, in 1948, he became the president of Columbia University, an Ivy League university in New York City. Nonetheless, he continued to advise the military on various matters. During his time at Columbia, he published his memoirs, which were titled "Crusade in Europe".
