The CFSP sees the North Atlantic Treaty Organisation (NATO) as responsible for the territorial defence of Europe and reconciliation. However, since 1999, the European Union is responsible for implementing missions such as peacekeeping and policing of treaties. A phrase often used to describe the relationship between the EU forces and NATO is "separable, but not separate". The same forces and capabilities form the basis of both EU and NATO efforts, but portions can be allocated to the European Union if necessary.
