Foreign policy begins at home, and in Europe and the United States the domestic drivers of foreign policy are shifting in important ways. The election of Donald Trump as U.S. president, the decision of British voters to leave the European Union, and popular pressures on governments of all stripes and colors to deal with the domestic consequences of global flows of people, money and terror all highlight the need for greater understanding of such domestic currents and their respective influence on U.S. and European foreign policies.

In this volume, European and American scholars take a closer look at the domestic determinants of foreign policy in the European Union and the United States, with a view to the implications for transatlantic relations. They examine domestic political currents, demographic trends, changing economic prospects, and domestic institutional and personal factors influencing foreign policy on each side of the Atlantic.
