Abstract: This article summarizes the thematic issue findings, focusing on the factors that contribute to stabilize or weaken EU–US relations. Seen together, the articles have systematically documented that there is a growing pressure on transatlantic relations both in multilateral institutional settings as well as in foreign and security policy. On the one hand, transatlantic relations within NATO are strengthening in the context of Russia’s new war in Ukraine, pushing Europe closer to the US and papering over disputes among European nations about the course of intra-European security cooperation. Shared norms and institutions as well as non-state actors with an interest in keeping the relationship strong for economic, strategic, or more normative reasons also serve to stabilize the relationship. On the other hand, longer-term geopolitical and economical structural changes together with domestic factors, particularly in the US, and in some cases diverging interests, suggest a parallel longer-term weakening of the relationship.
