President Eisenhower's support of brinkmanship during the Cold War had several effects on society in the United States. Brinkmanship was a strategy that involved pushing a dangerous situation to the brink of war to achieve favorable outcomes, which led to heightened tensions and fears of potential nuclear conflict. As a result, there was an increased focus on civil defense and the construction of bomb shelters to protect civilians in case of a nuclear attack. This sense of fear and insecurity also influenced cultural aspects, such as movies, literature, and media, which often portrayed themes of nuclear war and its aftermath. Additionally, the emphasis on military strength and preparedness impacted government spending and the growth of the military-industrial complex, which had both positive and negative effects on the economy and society.
