By

ABM Anti-ballistic missiles (ABMs) are designed to shoot down ballistic missiles (rockets carrying nuclear weapons) before they reach their targets.

arms race Massive military build-up, especially of nuclear weapons, by both the Soviet Union and the United States in an effort to gain military superiority.

brinkmanship Purposely escalating a dangerous situation to the limit (brink), while giving the impression that you are willing to go to war, in the hope of pressuring your opponents to back down.

broken arrow A nuclear bomb that is either lost, stolen, or accidentally launched that causes a nuclear accident. Though broken arrows made great movie plots throughout the Cold War, the most serious real-life broken arrow occurred on January 17, 1966 when a U.S. B-52 crashed off the coast of Spain. Though all four of the nuclear bombs aboard the B-52 were eventually recovered, radioactive material contaminated large areas around the crash site.

Checkpoint Charlie A crossing point between West Berlin and East Berlin when the Berlin Wall divided the city.

Cold War The struggle for power between the Soviet Union and the United States that lasted from the end of World War II until the collapse of the Soviet Union. The war was considered "cold" because the aggression was ideological, economic, and diplomatic rather than a direct military conflict.

communism An economic theory in which collective ownership of property leads to a classless society.

Communism The form of government in the Soviet Union in which the state owned all means of production and was led by a centralized, authoritarian party. This was viewed as the antithesis of democracy in the United States.

containment Fundamental U.S. foreign policy during the Cold War in which the U.S. tried to contain Communism by preventing it from spreading to other countries.

DEFCON An acronym for "defense readiness condition." The term is followed by a number (one to five) which informs the U.S. military to the severity of the threat, with DEFCON 5 representing normal, peacetime readiness to DEFCON 1 warning the need for maximum force readiness, i.e. war.

detente The relaxing of tension between the superpowers.

deterrence theory A theory that proposed a massive build-up of military and weaponry in order to threaten a destructive counter-attack to any potential attack. The threat was intended to prevent, or deter, anyone from attacking.

fallout shelter Underground structures, stocked with food and other supplies, that were intended to keep people safe from radioactive fallout following a nuclear attack.

first strike capability The ability of one country to launch a surprise, massive nuclear attack against another country. The goal of a first strike is to wipe out most, if not all, of the opposing country's weapons and aircraft, leaving them unable to launch a counter-attack.

glasnost A policy promoted during the latter half of the 1980s in the Soviet Union by Mikhail Gorbachev in which government secrecy (which had characterized the past several decades of Soviet policy) was discouraged and open discussion and distribution of information was encouraged. The term translates to "openness" in Russian.

missile gap The concern within the U.S. that the Soviet Union had greatly surpassed the U.S. in its stockpile of nuclear missiles.

mutually assured destruction MAD was the guarantee that if one superpower launched a massive nuclear attack, the other would reciprocate by also launching a massive nuclear attack, and both countries would be destroyed. This ultimately became the prime deterrent against a nuclear war between the two superpowers.

perestroika Introduced in June 1987 by Mikhail Gorbachev, an economic policy to decentralize the Soviet economy. The term translates to "restructuring" in Russian.
