The correct answer is B) Both interventions were about stopping the spread of Communism.

The U. S. intervention in the Middle East and the U. S. intervention in Latin America had the common goal of stopping the spread of Communism.

President Dwight Eisenhower introduced the concept of the "domino principle" in 1954. He tried to explain the continual risk that the U. S. had if Communism spread throughout the world. He considered that if one country fell under the influence of Communist's ideas, the probability was that the neighborhood countries would fall too, under the domino principle. That is why the U. S. intervention in the Middle East and the U. S. intervention in Latin America had the common goal of stopping the spread of Communism.

B. Both interventions were about stopping the spread of Communism.
