In June 1987, American President Ronald Reagan stood at Berlin Wall and demanded that Soviet premier Mikhail Gorbachev “Tear down this wall!” Less than three years later, amid civil unrest in November 1989, East German authorities announced that their citizens were free to travel to and from West Berlin. The concrete curtain would be lifted and East Berlin would be opened to the world. Within months, the Berlin Wall was reduced to rubble by jubilant crowds anticipating the reunification of their city and their nation, which took place on October 3, 1990. By July 1991 the Warsaw Pact had crumbled, and on December 25 of that year, the Soviet Union was officially dissolved. Hungary, Poland, Czechoslovakia, and the Baltic States (Latvia, Estonia, and Lithuania) were freed from Russian domination.

Partisans fight to claim responsibility for the break-up of the Soviet Union and the ending of the Cold War. Whether it was the triumphalist rhetoric and militaristic pressure of conservatives or the internal fracturing of ossified bureaucracies and work of Russian reformers that shaped the ending of the Cold War is a question of later decades. Questions about the Cold War’s end must pause before appreciations of the Cold War’s impact at home and abroad. Whether measured by the tens of millions killed in Cold War-related conflicts, in the reshaping of American politics and culture, or in the transformation of America’s role in the world, the Cold War pushed American history upon a new path, one that it has yet to yield.
