Question

What led to increasing animosity toward the United States on the part of many Latin Americans? What did the Guatemalan incident reveal about American intentions?

Answer 1

This was a U.S. backed invasion that toppled the government of Jacobo Arbenz.  This began with Harry S. Truman but was carried out by Dwight Eisenhower.  This resulted in anti-American sentiment in Latin America and led to civil war in Guatemala.
