Bomb Drills

My mom was in elementary school during the Cold War. She remembered her school going through bomb drills every few months: her class would have to hide underneath their desks whenever a drill occurred, which seems silly to her now (hiding under desks would not provide much protection from any nuclear bombs). America was afraid Russians would them with missiles that were located in Cuba. My mother's third grade teacher would have the class pray that the Russians would not bomb America.
