Compare and contrast JFK's foreign policy to his predecessor's.Pay special attention to his Cold War objectives.

Both Pres. Eisenhower and Pres. Kennedy were firmly
committed to the containment of communism throughout the world.  The main difference
between them was in their visions of how to accomplish this
containment.

Eisenhower's time in office was known for the
policy of "massive retaliation" that was put forward by John Foster Dulles.  Under this
policy, the US reduced its conventional weapons (to save money) and relied on its
nuclear arsenal.  The idea was that the US would threaten to retaliate in a massive way
against any attacker.  This would deter attacks without the need for a large and
expensive conventional military.

By contrast, JFK's plan
was known as "flexible response."  JFK believed that massive retaliation did not give
him enough ways to respond to relatively small moves (like the communist infiltration of
South Vietnam).  He couldn't really attack the Soviet Union with nuclear weapons over
that, but he did want to try to stop the infiltration.  Therefore, Kennedy put much more
emphasis on conventional forces, and especially special forces like the Green Berets who
were supposed to be able to go in and teach natives how to fight on their
own.

So the major difference between the two is that
Eisenhower was going to rely on nuclear weapons while JFK pushed for a more flexible set
of responses to various threats.
