Abstract

This report assesses how changes in US foreign policy under a right-wing populist president affect the EU–US relationship and offers concrete policy recommendations on pressing issues. Focusing on the links between foreign-policy shifts, domestic polarization and antiliberal democratic trends, the report examines how domestic dynamics may constitute the most severe long-term challenge to transatlantic cooperation. It also evaluates specific policy challenges and opportunities for strengthening that cooperation in the years ahead.

By exploring developments in US foreign policies and how these are linked to domestic polarization and antiliberal democratic ideas, chapters in this report shed light on how this domestic factor poses a severe challenge to the transatlantic relationship. Authors focus on how the rise of right-wing populism – with an increasing portion of the population resisting globalization, international institutions, free trade and even democratic values on both sides of the Atlantic affects the transatlantic relationship.

Within each section of the report, a background chapter introduces the overarching debate, followed by three case studies focusing on observed changes, policy implications and recommendations for EU responses. The conclusion sums up key findings and provides recommendations for how the EU should respond to changing transatlantic relations.
