Lemnitzer felt that many of the United States’ future conflicts would be through coalitions so he pushed for a more unified system with European nations, straying away from the typical isolation system Americans were accustomed to. Shortly before the end of Dwight Eisenhower’s presidency, the president appointed Lemnitzer to the position of Chairman of the Joint Chiefs of Staff where he began to oversee the production of the American nuclear program. In 1963, Lemnitzer was chosen by President John F. Kennedy
to become the supreme commander of NATO. During his time as supreme commander, Lemnitzer navigated NATO through several intense political situations including the Cold War and the Greek and Turkish conflict over possession of Cyprus. General Lemnitzer served as NATO supreme commander until 1969, when he retired from military duty after an illustrious career. During his career of nearly fifty years, Lemnitzer obtained many prestigious military awards including the Army Distinguished Service Medal, the Navy Distinguished Service Medal, the Air Force Distinguished Service Medal, and the Silver Star, as well as several other awards both foreign and domestic
. After his retirement, Lemnitzer was appointed to the Rockefeller Commission, which examined a possible conspiracy with the CIA’s involvement with the Kennedy assassination.
