World leaders paid tribute to the bravery of those who broke the shackles of their communist regimes back in 1989 and forced change throughout Eastern Europe. German Chancellor Angela Merkel, who grew up in East Germany, recalled how she experienced that night and said it was a day of celebration for the whole of Europe. The fall of the Wall has come to symbolize the collapse of the communist regimes across central and Eastern Europe. And it led to the unification of Germany one year later. Twenty years on, the achievements of those 1989 revolutions are clear: democracy, free market economies and the loosening of borders. But have there been missed opportunities as well, for example here in Germany? Helen Seeney put that question to analyst Heinz Schulte.
