Terrorism is a good example of the new security threats that seriously challenge what is still a largely state-centered security system. Many of today's most serious threats are global in scale. The traditional military force is far from adequate to confront these new challenges. It is crucial that the military effort will be coupled with other measures, such as international police cooperation, financial investigation and cooperation and diplomacy. Therefore a crucial task for the international community is to continue improving the civilian preparedness in crisis management. Here the OSCE can plan an important role. The terror attacks of September 11 accelerated the transformation process of the European security system. It had in particular an influence on NATO's role. Even though NATO invoked its Article 5 mutual protection clause the US chose not to act militarily through the alliance.

The purpose of this workshop is to explore the new post-cold war security agenda and to examine future security challenges facing Europe and the wide international system. It will also assess the relevance and utility of different actors and instruments for tacking these new security challenges, and examine options for the future institutional development of European security.

Developments in foreign policies at both sides of the Atlantic may significantly change US-EU security relations in the years ahead. The EU and NATO face new challenges, such as the eastward enlargement of the EU and NATO, and emerging potential threats, such as regional conflicts, terrorism, internationally organized crime, and proliferation of weapons of mass destruction. Crisis management is the paradigm that forms the cornerstone of the operational efforts of NATO and the European Union (EU) has already shifted toward this type of activity. Both members of the EU in the framework of the "Petersberg Tasks" and members of NATO or PfP participate in crisis management, peace-keeping, humanitarian action and peace-making/peace-enforcement operations. The tasks of members of NATO and the EU would be blurred in the field of crisis management.

One of the central points of controversy amongst both academics and policy-makers is the nature and significance of security in the post-cold war world. For much of the cold war period the concept of security was largely defined in militarized terms. The main focus for investigation for both academics and statesmen- and women tended to be the military capabilities required by states to deal with the threats perceived to face them. More recently, however, the idea of security has been broadened to include political, economic, societal and environmental aspects as well as military. Above all, it is necessary for the European Union to develop a broader and more comprehensive approach to security. Future security challenges will not primarily concern territorial defense. While states will continue to pay attention to their territorial defense, other security challenges are likely to demand greater attention in the future. Human rights, environmental degradation, political stability and democracy, social issues, cultural and religious identity and migration are issues which are becoming ever more important for security and conflict prevention.

Though the possibility of a regional war remains, as in the Balkans and in Afghanistan, mass invasion and total war have ceased to be a threat to East or West. Instead, most threats to national security in Europe today are not directly military. They may evolve out of economic problems, ethnic hostility, or insecure and inefficient borders, which allow illegal migration and smuggling. Or they may be related to organized crime and corruption, both of which have an international dimension and undermine the healthy development of democracy and the market economy. Moreover, the proliferation of military or dual technology, including weapons of mass destruction - chemical and biological as well as nuclear - and their means of delivery, and the revolution in information technology present special challenges.

NATO and the EU have responded to Europe's evolving post-cold war order by redefining and expanding their roles and objectives. Despite institutional differences, the activities of NATO and the EU complement each other to strengthen the economic, political, and military dimensions of regional security and stability. Founded as a defensive alliance, NATO has revised its strategic concept to respond to the broader spectrum of the new threats now facing greater Europe - those ranging from traditional cases of cross-border aggression to interethnic conflicts and acts of terrorism. Furthermore, NATO is facilitating the integration and eventual membership of Central and Eastern European nations in the transatlantic security community. The EU has likewise emphasized regional integration as being key to a safe and stable Europe, particularly through the deepening of political and economic ties among current members and through extending EU membership to CEE countries.
