The Eisenhower-Dulles era was a Pax Americana enforced by terror. The administration ensured U.S. postwar global dominance by threatening enemies with nuclear annihilation or with coups and assassinations. It was empire on the cheap, a product of Ike’s desire to avoid another large-scale shooting war as well as the imperial burdens that had bankrupted Great Britain. By leveraging the U.S. military’s near monopoly on nuclear firepower, the president hoped to make war an unthinkable proposition for any and all American adversaries.
