Answer:
Correct answer is STALIN.
Step-by-step explanation:
Stalin is the correct answer as he was responsible for the transportation of millions of people. It is estimated that during 1920s and 1930s more than 100 thousand Koreans were moved towards the East. On the other side, during Stalin's reign around 50 thousand Soviet Greeks were transferred.
Gorbachev and Khrushchev were not to blame for this process, while Eisenhower was American, not Soviet leader.
