Truman was the one who adopted a policy of containment. This (arguably) aggressive approach was what influenced America to get into wars such as the Korean War and other smaller conflicts. Meanwhile, Eisenhower was a bit less aggressive. Although his Secretary of State Dulles preached Brinksmanship and was very anti-Soviet, Eisenhower himself was somewhat against this, as shown when he did nothing to prevent the Hungarian Revolt. He also sought to increase U.S-Soviet Relations in the Spirit of Geneva, but the U-2 Incident pretty much erased most of his progress.
