What does President Johnson stationing warships off the Dominican coast, the CIA helping engineer a truck drivers' strike that paralyzed Chile, and the CIA urging the Chilean military to take action say about U. S. foreign policy?
that protectionism was part of the mission
that transportation and the military were of equal importance
that the CIA could be called on to maintain free elections
that the major goal was to fight communism

The correct answer is D) that the major goal was to fight communism.

All these President Johnson's actions say about U.S. foreign policy that the major goal was to fight communism.

Let's have in mind that those were the Cold War years in which the United States and the Soviet Union had many disputes and conflicts trying to defeat each other in the arms race and spread Communists -in the case of the Soviet Union- and to stop it, in the case of the United States. We have to remember that the world was on the brink of another war due to the Cuban Missiles Crisis of October 1962.
