Question

What were two reasons the Reagan administration used to justify invading Grenada in 1983?

Answer 1

The Invasion of Granada, military operation codenamed Urgent Fury, was an attack on the island nation of Grenada by the United States and several other Caribbean nations in response to the coup d'état perpetrated by Hudson Austin and his Cuban-Soviet military alliance. On October 25, 1983, the United States, Barbados, Jamaica and members of the Organization of Eastern Caribbean States disembarked troops in Granada, defeated the resistance of Granada and Cuba and overthrew the government of Hudson Austin.

The US officials indicated that the reasons for the military action were the coup and the general political instability in a country near their own borders, as well as the presence of American medical students in the University of St. George of Granada.

Answer 2

The nation was leaning towards Communism
