This chapter examines the normative principles underlying the European Union's foreign policy and whether there are inconsistencies therein. Drawing on a distinction between the principles of sovereignty, human rights, and a common good, the chapter challenges the notion that the EU is a distinctive foreign policy actor. Each of these principles points to a different perspective on how international politics should be organized, and each would take the EU's foreign policy in different directions. The chapter shows that the unresolved tensions in the EU's internal constitution, between its cosmopolitan vocation and the ambition of (EU) nation building, are also reflected in the EU foreign policy.
