Bay of Pigs Invasion

The story of the failed invasion of Cuba at the Bay of Pigs is
one of mismanagement, overconfidence, and lack of security. The
blame for the failure of the operation falls directly in the lap of
the Central Intelligence Agency and a young president and his
advisors. The fall out from the invasion caused a rise in tension
between the two great superpowers and ironically 34 years after the
event, the person that the invasion meant to topple, Fidel Castro,
is still in power. To understand the origins of the invasion and
its ramifications for the future it is first necessary to look at
the invasion and its origins.
