Answer:
The United States sent $400 million to both nations to be used in resisting communism.
Explanation:
The United States eagerly supported both nations in this particular time, since its primary goal was to reduce tension between the two in order to keep its own government officials active in <em>worldwide</em> conflicts.
Also, I would like to add that the United States also intervened in other aspects, as are listed below in three points.
#1: We (the U.S.) established missiles in the two countries in order to keep constant peace between them, not just momentary compromise.
#2: While we actively engaged in Greece's political system and aided them in a multitude of ways, we were not as direct with Turkey.
#3: We also sent elected military advisers to assist the nations - in this case not biased towards Greece - in order to strengthen their own military groups.
Hopefully this strengthened your overall knowledge of this subject! Tell me if you need any further assistance. ( :
