The Cold War had a tremendous impact on the everyday lives of Americans. For example, students in public schools during the 1950's often had to practice "Duck and Cover" drills. These drills forced students to cover their head with their hands and to hide underneath desks. One of the reasons students practiced these drills was in case nuclear warfare between the United States and Soviet Union took place.
In the aforementioned scenario, students would be ducking and covering to protect themselves from the effects of a nuclear attack. This type of drill showed the Americans were constantly in fear of what might happen next between the US and the Soviet Union.
