A period of almost two weeks during the
John F. Kennedy administration, in October of
1962, during which the
United States discovered that the
Soviet Union was installing
ICBM's in
Cuba. The U.S. insisted on the withdrawel of the missiles and blockade
?d Cuba. Concrete proof of the existance of the
missiles was provided by the
U2 spy plane. The Soviet Union wanted the U.S. to remove its missiles from
Turkey. The Soviet Union backed down about the Cuban missiles, and the US removed the missiles from Turkey some time later. The blockade was called a "quarantine" because declaring a "blockade" would be a declaration of
war.
