Since the end of the Cold War, international co-operation has been central to Denmark in terms of foreign, security and defense policy.
As a result of the EU defense opt-out, Denmark does not contribute to EU military operations. However, Denmark participates in other areas, such as cooperation on military mobility, internal security (Frontex) and cyber.
Denmark has participated in UN peacekeeping missions since the establishment of the first mission in 1948.
International emergency preparedness cooperation primarily includes civil protection, but also health preparedness, marine environmental preparedness, etc.
