The publication examines the evolution of transatlantic relations in an international context increasingly marked by fragmentation and rising tensions, highlighting the effects of divergences between the United States and the European Union on multilateralism, international trade, and security cooperation. It underscores how recent shifts in U.S. foreign policy, particularly under the Trump administration, have contributed to a more unstable and asymmetric relationship, with direct implications for the EU’s capacity to act.

The report also explores the strategies adopted by the European Union in response to this scenario, emphasizing its pursuit of greater strategic autonomy, deeper internal integration, and the expansion of external partnerships. In addition, it addresses the challenges posed by the reconfiguration of the global order, including the weakening of multilateral institutions and the role of initiatives such as the EU–Mercosur agreement, highlighting both their potential and their limitations in an increasingly competitive international environment.
