Jeffrey Sachs highlights the foreign policy triumphs of John F. Kennedy’s presidency and the crusade for world peace that he focused on in office. The last great campaign of John F. Kennedy’s life was not the battle for reelection he did not live to wage, but the struggle for a sustainable peace with the Soviet Union. To Move the World: JFK’s Quest for Peace looks at October 1962 to September 1963, when JFK used his political skills to establish more peaceful relations with the Soviet Union and to slow down the proliferation of nuclear arms.
