Answer:
According to Domino Theory, a communist nation could drag nations close to its area of influence into communism. Therefore, a communist Vietnam could drag Malaysia into communism.
Step-by-step explanation:
The Domino theory was a theory used mainly by the United States during the Cold War. The theory meant that if the Communists succeeded in taking over a country without the United States intervening, more countries would risk giving in to the Communists because they would see that they could not expect any help. The Domino Theory was first used by President Dwight D. Eisenhower in a press conference on April 7, 1954. He believed that if France lost the war in Indochina, communism would spread to Burma, Thailand, Malaya and Indonesia. Therefore, the threat to Japan, the Philippines, Australia and New Zealand would be acute.
