This paper--given as a speech in The Hague in December 1998--presents relevant elements of four broad themes making up a picture of European security over the next decade. The first is the nature of Europe, an issue which is not yet settled. the second is four trends: the evolution of Russia, the rise of the market state, the unification of Germany, and the weakness of European institutions. Third is the transatlantic agenda, particularly the need to engage Russia, to proceed with European integration, and to face the consequences of globalization. Last are the tasks ahead: To build on common values, to strengthen European institutions, to bring all European countries into the process of European integration, to develop the so-called Transatlantic Agenda, and to focus NATO on threats from beyond NATO's borders.
