The Berlin Wall had made its mark forever in history, as the physical icon of the Cold War. However, while many people wanted to see the collapse of the wall and make it happen, there was opposition in many places as well.
The fall of the Wall caused anxiety more than joy at the highest levels of authority. The US government and the Allied bloc were anxious about what would happen with a reunited Germany. For instance, solidarity hero Lech Walesa felt that events were taking place too fast and should the wall collapse, much emphasis would be placed in helping GDR (East Germany) and therefore will leave Poland in the background.
Also, then British Prime Minister Margaret Thatcher had told Mikhail Gorbachev that "Britain and Western Europe are not interested in the unification of Germany. The words written in the NATO communiqué may sound different, but disregard them." Having known this, top Gorbachev aide Anatoly Chernyaev concluded that Thatcher wanted to prevent unification "with our hands" and not her own.
Finally, after the collapse of the Wall, then French President Francois Miterrand warned Thatcher that Europe had to bear its consequences, especially since a unified Germany would be able to cover more ground than what Adolf Hitler did.
However, one of the few highest-level expressions of joy over the fall of the Wall occurred in Moscow. In the diary of Gorbachev aide Chernyaev, he wrote on November 10that "The Berlin Wall has collapsed. This entire era in the history of the socialist system is over… That is what Gorbachev has done. And he has indeed turned out to be a great leader. He has sensed the pace of history and helped history to find a natural channel." This sentiment was shared with by many other citizens in Europe, especially in East and West Berlin, where many people wanted the collapse of the Wall and the reunification of Germany without such a forced physical barrier.
