How did the Eisenhower administration plan to contain Communism?
The Eisenhower administration planned to contain communism in many ways. The one that is most uniquely associated with the Eisenhower administration is the doctrine of massive retaliation. This meant that the US would retaliate against any attack with a massive barrage of nuclear weapons. By putting forth this doctrine, Eisenhower hoped to get "more bang for the buck."
Eisenhower felt that it would be too expensive to maintain enough conventional forces to deter communist aggression all over the world. So he felt that keeping a massive nuclear arsenal would be more cost effective. He threatened to meet any attack on US interests with massive nuclear retaliation. By threatening this, he hoped to deter and contain communist expansion without having to pay for the soldiers, ships, tanks, artillery, etc., that would be needed to deter them in a conventional way.
