What has changed in the world order rules? The Konrad-Adenauer-Stiftung hosted the final panel of the Georgia Defence and Security Conference (GDSC). The fourth thematic platform focused on key challenges of the global and European security, threat assessment and deliberation of policy responses.

Dynamics of crises on Europe’s southern and eastern flank, coupled with the inflow of migrants and increasing terrorist threat had a negative impact on regional security environment. The panel discussions will stress the importance of Euro-Atlantic strategic partnership and intensified cooperation between allies and partners in response to current challenges.
