Arms Race Superpowers engaged in weapons race Both sides developed nuclear weapons To reduce the threat of war, the two sides held
disarmament talks One agreement was intended to limit the use
of anti-ballistic missiles (ABMs) ABMs were used to shoot down missiles
launched by hostile nations

Minuteman III MIRV launch sequence:1. The missile launches out of its silo by firing its first stage boost motor (A).2. About 60 seconds after launch, the 1st stage drops off and the second stage motor (B) ignites. The missile shroud is ejected.3. About 120 seconds after launch, the third stage motor (C) ignites and separates from the 2nd stage.4. About 180 seconds after launch, third stage thrust terminates and the Post-Boost Vehicle (D) separates from the rocket.5. The Post-Boost Vehicle maneuvers itself and prepares for re-entry vehicle (RV) deployment.6. The RVs, as well as decoys and chaff, are deployed during backaway.7. The RVs and chaff re-enter the atmosphere at high speeds and are armed in flight.8. The nuclear warheads detonate, either as air bursts or ground bursts.
A multiple independently targetable reentry vehicle (MIRV) is a collection of nuclear weapons carried on a single intercontinental ballistic missile (ICBM) or a submarine-launched ballistic missile (SLBM). Using a MIRV warhead, a single launched missile can strike several targets, or fewer targets redundantly. By contrast a unitary warhead is a single warhead on a single missile.

Anti-Ballistic Missiles ABMs were considered a threat because they
could give one side more protection, which might encourage it to attack
During the 1980s, President Ronald Reagan proposed a missile defense program called “Star Wars”
Other agreements limited the number of nuclear weapons that nations could maintain, which eased Cold War tensions

Anti-Ballistic Missiles The easing of tensions was called the era of
détente Détente is a relaxing of Cold War tensions
during the 1970s Both superpowers were talking more with less
direct hostile threats Détente ended, however, when the USSR
invaded Afghanistan in 1979

Cuba and Fidel Castro During the 1950s, Fidel Castro led a revolution
in Cuba and became the Cuban leader To bring down Cuba’s communist regime, U.S.
President John F. Kennedy supported a CIA-backed invasion of Cuba (Bay of Pigs)(1961), but the invasion failed
One year later, the Soviets shipped nuclear missiles to Cuba causing fear of a nuclear war

Spreading Communism USSR wanted to spread communist ideology
around the world When Khrushchev came to power, he eased
censorship and increase tolerance However, repression returned under Leonid
Brezhnev, the next Soviet leader American leaders pursued a policy of
containment This was a strategy of keeping communism
from spreading to other nations (to “contain” it)

Red Scare A “Red Scare” in the USA resulted in Senator
Joseph McCarthy leading an internal hunt for communists in the government and military
The House (of Representatives) Un-American Activities Committee (HUAC) also sought out communist sympathizers
People suspected of being communists were called to testify before a congressional committee as to their alleged activities in government, society, business, etc.
