Answer:
The sponsoring and supporting of military dictators
Step-by-step explanation:
The United States had and still has a very big interest in Latin America. During the 20th century, the United States managed to do numerous terrible things to the people in this region because of their own interest. One of those things was that they were sponsoring and supporting military dictators. Those military dictators were terrorizing the people, and were regressing their countries instead of moving them forward. The people in Latin America naturally grew to dislike the United States, as they were the prime responsible side for their suffering, thus the anti-American sentiment became very big, and in general still is.
