When East Germans first crossed through the Berlin Wall on 9 November 1989, no one knew that the consequences of this one small act would have global ramifications, bringing about the end of the forty year Cold War, and transforming the framework of global politics. The past twenty years have shown that the fall of the Berlin Wall is far from being just an end-point; rather, it was the beginning of a new era in German-American relations, in transatlantic cooperation, and in global affairs. The authors of German-American Issues 12 – J.D. Bindenagel, Manuel Lafont Rapnouil, Klaus Larres, and Holger Wolf – reflect on these and other consequences of the events of November 1989, proving that that historic moment is just as relevant today as it was twenty years ago.
