European integration has proved phenomenally successful. The whole thing
had just one decisive shortcoming, forced upon it by history: it was not the
whole of Europe, but merely its free part in the West. For fifty years the
division of Europe cut right through Germany and Berlin, and on the eastern
side of the Wall and barbed wire an indispensable part of Europe, without
which European integration could never be completed, waited for its chance
to take part in the European unification process. That chance came with the
end of the division of Europe and Germany in 1989/90.
Robert Schuman saw this quite clearly back in 1963: "We must build the
united Europe not only in the interest of the free nations, but also in
order to be able to admit the peoples of Eastern Europe into this community
if, freed from the constraints under which they live, they want to join and
seek our moral support. We owe them the example of a unified, fraternal
Europe. Every step we take along this road will mean a new opportunity for
them. They need our help with the transformation they have to achieve. It is
our duty to be prepared."
Following the collapse of the Soviet empire the EU had to open up to the
east, otherwise the very idea of European integration would have undermined
itself and eventually self-destructed. Why9 A glance at the former
Yugoslavia shows us the consequences, even if they would not always and
everywhere have been so extreme. An EU restricted to Western Europe would
forever have had to deal with a divided system in Europe: in Western Europe
integration, in Eastern Europe the old system of balance with its continued
national orientation, constraints of coalition, traditional interest-led
politics and the permanent danger of nationalist ideologies and
confrontations. A divided system of states in Europe without an overarching
order would in the long term make Europe a continent of uncertainty, and in
the medium term these traditional lines of conflict would shift from Eastern
Europe into the EU again. If that happened Germany in particular would be
the big loser. The geopolitical reality after 1989 left no serious
alternative to the eastward enlargement of the European institutions, and
this has never been truer than now in the age of globalization.
