Question

1. how did president john kennedy react to installation of nuclear - tipped missiles in cuba in 1962?

he ordered strategic air strikes to destroy the launching sites and surrounding defenses.
he refused to force the issue of the missiles with the ussr in fear of a nuclear war.
he set up a naval quarantine of cuba and demanded removal of missiles by the ussr.
he required cuba to destroy the missile launching sites and disarm their fighting forces.

Explanation:

During the 1962 Cuban Missile Crisis, President John Kennedy implemented a naval quarantine (referred to as a quarantine instead of a blockade to avoid legal classification as an act of war) of Cuba to prevent additional Soviet missiles from arriving, while publicly demanding the USSR remove the already deployed nuclear-tipped missiles. The other options are incorrect: he did not order immediate air strikes, did not refuse to address the issue, and did not demand Cuba itself destroy the sites directly as the primary response.

Answer:

He set up a naval quarantine of Cuba and demanded removal of missiles by the USSR.
