The EU and the US, mainly through NATO, have been successful in securing peace and prosperity in Europe during the Cold War and in promoting peace beyond Europe after 1990. With the emergence of new powers and the rise of multipolarity, however, it is no longer apparent that transatlantic relations are indispensable and ways must be found to make sure that the relationship remains relevant. The EU and the US currently relate poorly to each other and as a result do not obtain the best possible outcome from their combined resources. Two elements are key to improving transatlantic relations: an inclusive policy towards Turkey (in the strategic interests of both the EU and the US); and more permanent and workable structures suited to the realities of the 21st century.
