The purpose of this article is to analyse the main characteristics of the EU’s foreign and security policy that can affect its functioning at present and in the future. Being part of the broader category which is the EU’s external policy, the EU’s foreign and security policy is plagued with numerous flaws. Reducing their impact would greatly strengthen this policy, but at the same time this depends on the resolution of the main axiological dilemma. It concerns the future shape of the whole European Union, which means that the EU needs to clearly formulate its finalité politique. The resolution of this dilemma will determine not only the future of the EU, but also the present and future shape of its foreign and security policy.
