Answer:
The answer is C. The Cuban Missile Crisis.
Step-by-step explanation:
The Cuban Missile Crisis was a 13-day confrontation between the United States and the Soviet Union in October 1962 over the installation of nuclear-armed Soviet missiles on Cuba, just 90 miles from U.S. shores. The crisis brought the world to the brink of nuclear war, but it also helped to break conservative resistance to social programs.
The crisis showed that the United States was vulnerable to attack, and it led to a renewed sense of urgency about the need to address social problems such as poverty and inequality. In the wake of the crisis, President Kennedy proposed a number of new social programs, including the War on Poverty and the Civil Rights Act of 1964. These programs were met with some resistance from conservatives, but they were ultimately successful in helping to break down the barriers that had prevented the government from addressing social problems in the past.
The Cuban Missile Crisis was a watershed moment in American history. It helped to shape the Cold War, and it also had a profound impact on domestic politics. The crisis helped to break conservative resistance to social programs, and it paved the way for a more progressive era in American history.
