The collapse of the Soviet empire marked the end of the bipolar power constellation in Europe and necessitated the search for a new balance. German reunification, which previously seemed improbable and undesirable, occurred before the unification of Europe. This development, which can be seen as a reversal of the post-war order, positions Germany, albeit smaller, as an economic superpower with the potential to become a political and military power again. The emerging instability in the East may lead to seeking support in Germany and to the reawakening of German hegemonic tendencies. For neighboring countries, including a divided Czechoslovakia, this prospect is worrying. Historically complex relations with Germany and the specific situation after the expulsion of Germans from the border regions may impact future European architecture. In the context of uncertain European unification and the absence of clear peace aims for Europe, Germany's future role and its relationship with Europe remain an open question.
