The Cuban Missile Crisis was a 13-day Cold War standoff in October 1962 over Soviet nuclear missiles in Cuba. It is considered the closest the Cold War came to nuclear war.

What it is

In October 1962, U.S. reconnaissance discovered Soviet missile sites under construction in Cuba. President John F. Kennedy ordered a naval quarantine, and the superpowers faced off over the removal of the missiles. The confrontation lasted 13 days and ended with Soviet withdrawal.

Why it matters

The crisis is widely seen as the moment the Cold War nearly turned hot. It pushed both sides toward direct communication and arms control, including the 1963 Washington-Moscow hotline and the Partial Nuclear Test Ban Treaty. For Canada, it heightened nuclear-alert concerns within the broader NATO context.

Key details

The Soviet Union agreed to remove its missiles from Cuba in exchange for a U.S. pledge not to invade the island. A secret understanding also led the United States to remove its Jupiter missiles from Turkey. The crisis underscored the dangers of nuclear brinksmanship and the need for crisis management.

In short

  • 13-day standoff in October 1962 over Soviet nuclear missiles in Cuba.
  • U.S. imposed a naval quarantine; Kennedy and Khrushchev negotiated a resolution.
  • Soviet missiles removed; U.S. pledged not to invade Cuba.
  • Led to the hotline and the 1963 Nuclear Test Ban Treaty.
Canadian angle

The crisis affected Canada as part of the Cold War security environment in North America, including heightened nuclear-alert concerns and the broader NATO context for Canadian foreign and defence policy.
