The correct answer to this open question is the following.
The fall of the Berlin wall might have impacted the relationship between the Soviet Union and the United States in that this event represented the culmination of tense and conflictive relationships during the Cold War years in which both nations competed in the arms race, meanwhile the Soviet Union tried to spread Communism in many places and the United States tried to stop it through the foreign policy of containment.
