This isn't necessarily a bad thing, because the West itself is no longer as solid an entity as it was in 1989. As long as the underpinnings -- freedom, peacefulness, democracy, the constitutional state and the social market economy -- remain untouched, Germany also has a right to its own path within its alliances, the EU and NATO.
Perhaps the 1989 revolutionaries didn't have many of these developments in mind. But they didn't just remove the GDR from maps; they also changed Germany as a whole.
Revolutions arise from obstinacy. People are dissatisfied with what they are told and they develop new ideas. That was how it was in 1989, in Leipzig and elsewhere. Perhaps it's just a coincidence, but 25 years later we are now living in an obstinate country, which is a new sensation for Germans in the postwar era.
