Answer:
(D) The question of whether to use atomic weapons against the Japanese
This was the main cause of tension between President Truman and Soviet premier Joseph Stalin near the end of World War II.
Step-by-step explanation:
There were a lot of trust issues between President Truman and Soviet premier Joseph Stalin. U.S was against communism which was encouraged by Soviet Union.
There were settling matters related to Germany and Poland. Then, U.S had kept the atom bomb as a secret to Soviet Union. U.S was thinking of throwing the bomb as a necessity for complete invasion. Also, Truman wanted to spread democracy and prevent communism, but Soviet wanted communism. All these issues led to a cold war between the two countries.
