Dwight D. Eisenhower
The U.N. speech was well received but the Soviets never acted upon it, due to an overarching concern for the greater stockpiles of nuclear weapons in the U.S. arsenal. Indeed, Eisenhower embarked upon a greater reliance on the use of nuclear weapons, while reducing conventional forces, and with them the overall defense budget, a policy formulated as a result of Project Solarium and expressed in NSC 162/2. This approach became known as the "New Look", and was initiated with defense cuts in late 1953.

Q: When did Eisenhower begin to cut the defense budget?
1953
