Security and defense are back at the center of European politics. Russia’s war in Ukraine, an unsettled transatlantic bargain, and rapid technological change have forced governments to rethink deterrence, rearmament, and the alliances that keep the peace. This hub is the gateway to analysis across the security and defense agenda: NATO deterrence and posture, regional security from the Baltic to the Black Sea, defense innovation and industrial capacity, and the defense spending needed to sustain it. NATO deterrence now rests on credible forces along the eastern flank, and defense innovation is reshaping how those forces fight. Fellows and analysts, including specialists in defense and military affairs, assess force structure, defense spending, and burden-sharing across Washington and European capitals. Explore expert analysis and commentary spanning NATO, regional security, and the defense of the Euro-Atlantic community.
