Cuban Missile Crisis

Overview

• Occurred: October 16–28, 1962

• Main countries involved:

  • United States

  • Soviet Union

  • Cuba

• Often considered the closest the world ever came to nuclear war

• Took place during the height of the Cold War

Background Causes

Cold War Tensions

• Ongoing ideological conflict between:

  • Capitalist U.S.

  • Communist Soviet Union

• Arms race: both nations rapidly building nuclear weapons.

• Mutually Assured Destruction (MAD) — both sides knew nuclear war would mean total destruction.

Cuban Revolution (1959)

• Fidel Castro overthrew dictator Fulgencio Batista.

• Castro established a communist government.

• Cuba became allied with the Soviet Union.

Bay of Pigs Invasion (1961)

• Failed U.S.-backed invasion of Cuba.

• Approved by John F. Kennedy.

• Strengthened Castro’s position.

• Pushed Cuba closer to the Soviet Union for protection.

Soviet Missiles in Turkey

• U.S. had nuclear missiles stationed in Turkey.

• Turkey bordered the Soviet Union.

• The Soviets viewed this as a threat.

• This becomes important later in negotiations.

Why the Soviets Placed Missiles in Cuba

• Protect Cuba from future U.S. invasion.

• Shift nuclear balance (U.S. had more missiles).

• Place nuclear weapons close to the U.S. mainland.

• Political pressure on Soviet leader Nikita Khrushchev to appear strong.

Discovery of the Missiles

• October 14, 1962:

  • U.S. U-2 spy plane photographed missile sites in Cuba.

• October 16:

  • Kennedy was informed.

  • Executive Committee (ExComm) formed to discuss options.

Kennedy’s Options (Debated in ExComm)

• Do nothing.

• Diplomatic pressure.

• Airstrike on missile sites.

• Full-scale invasion of Cuba.

• Naval blockade (called a “quarantine”).

Kennedy chose a naval blockade to avoid immediate war.

The Blockade (Quarantine)

• Announced October 22, 1962 in a televised address.

• U.S. Navy surrounded Cuba.

• Prevented Soviet ships carrying missiles from entering.

• U.S. military went to DEFCON 2 (one step from nuclear war).

This was an extremely dangerous moment:

• If Soviet ships tried to break the blockade, war could start instantly.

Khrushchev’s Response

• Initially condemned U.S. actions.

• Soviet ships approached the blockade line.

• Eventually, some ships turned around.

The Two Letters

First Letter (October 26)

• Khrushchev offered:

  • Remove missiles if U.S. promised not to invade Cuba.

• Tone was emotional and conciliatory.

Second Letter (October 27)

• More aggressive.

• Demanded:

  • Removal of U.S. missiles from Turkey.

Kennedy publicly responded only to the first letter.

Privately, the U.S. agreed to remove missiles from Turkey (secret deal).

Resolution (October 28, 1962)

• Khrushchev agreed to remove Soviet missiles from Cuba.

• U.S. agreed:

  • Not to invade Cuba.

  • Secretly remove missiles from Turkey.

Crisis ended after 13 days.

Why It Was So Dangerous

• Both sides had nuclear weapons ready.

• A U.S. U-2 plane was shot down over Cuba.

• U.S. military leaders pushed for invasion.

• One Soviet submarine nearly launched a nuclear torpedo.

  • A Soviet officer, Vasili Arkhipov, refused to authorize it.

  • His decision likely prevented nuclear war.

Immediate Effects

• Established a “hotline” between Washington and Moscow.

• Both sides realized how close they came to destruction.

• Led to better communication between superpowers.

Long-Term Effects

Nuclear Test Ban Treaty (1963)

• Limited nuclear weapons testing.

• Signed by:

  • U.S.

  • Soviet Union

  • United Kingdom

Shift in Cold War Strategy

• Movement toward détente (relaxed tensions).

• Greater awareness of nuclear danger.

• MAD doctrine taken more seriously.

Who “Won”?

• U.S. publicly appeared to win:

  • Missiles removed from Cuba.

• Soviet Union gained:

  • U.S. missiles removed from Turkey.

  • U.S. promise not to invade Cuba.

In reality:

• Both sides stepped back from the brink.

• The real “winner” was avoiding nuclear war.
