ABSTRACT
This chapter focuses on the capacity of the US and the European Union (EU) to deal with the dramatic changes that emerged in the international system during the 2010s. It explains the institutional dysfunctions in the EU and explores inevitable dilemmas that the US and EU had and have to face in order to identify a foreign policy approach appropriate for dealing with the challenges of a no one's world. The chapter also focuses on US foreign policy during the two Obama administrations and EU foreign policy after the coming into force of the Lisbon Treaty on 1 December 2009. Foreign policy analysis offers the model for doing that through the analytical connection between domestic politics and the international system, as developed from the pioneering work of James N. Rosenau in 1971 to the most recent work by Christopher Hill in 2003.
