In the past, European integration was based on the "Monnet method" with
its communitarization approach in European institutions and policy. This
gradual process of integration, with no blueprint for the final state, was
conceived in the 1950s for the economic integration of a small group of
countries. Successful as it was in that scenario, this approach has proved
to be of only limited use for the political integration and democratization
of Europe. Where it was not possible for all EU members to move ahead,
smaller groups of countries of varying composition took the lead, as was the
case with Economic and Monetary Union and with Schengen.
Does the answer to the twin challenge of enlargement and deepening, then,
lie in such a differentiation, an enhanced co-operation in some areas?
Precisely in an enlarged and thus necessarily more heterogeneous Union,
further differentiation will be inevitable. To facilitate this process is
thus one of the priorities of the intergovernmental conference.
However, increasing differentiation will also entail new problems: a loss
of European identity, of internal coherence, as well as the danger of an
internal erosion of the EU, should ever lar areas of intergovernmental
co-operation loosen the nexus of integration. Even today a crisis of the
Monnet method can no longer be overlooked, a crisis that cannot be solved
according to the method's own logic.
That is why Jacques Delors, Helmut Schmidt and Valéry Giscard d'Estaing
have recently tried to find new answers to this dilemma. Delors' idea is
that a "federation of nation-states", comprising the six founding states of
the European Community, should conclude a "treaty within the treaty" with a
view to making far-reaching reforms in the European institutions. Schmidt
and Giscard's ideas are in a similar vein, though they place the Euro-11
states at the centre, rather than just the six founding states. As early as
1994 Karl Lamers and Wolfgang Schauble proposed the creation of a "core
Europe", but it was stillborn, as it were, because it presupposed an
exclusive, closed "core", even omitting the founding state Italy, rather
than a magnet of integration open to all.
