Before the Berlin Wall was created, there was tension between the United States and the Soviet Union, due to the major difference between their economic system, capitalism and communism.The difference caused the Cold War, in which the Berlin wall was created. When the wall was created, there was slightly less tension. However the tension eventually increased to a tension that was larger than the one before. This tension between the United States and the Soviet Union could have been enough to start World War 3, but that never occurred.
After the Berlin Wall fell, Berlin was united. Germany was eventually united and the tension between the United States and the Soviet Union decreased dramatically. East Germany was no longer a Communist nation after the reunification. With this, East Germany was no longer an enemy to the United States. This opened up trade between East Germany and the United States.
