In the face of growing strategic uncertainty, Europe must rethink its security and defense policies, considering the diverse priorities of its member states as well as strategic partners outside the EU. For social democrats, this moment represents both a challenge and an opportunity to steer the EU towards reform and renewed relevance on the global stage. Progressive forces must reclaim the security agenda, reframing security not only in military terms but also in terms of human security, democracy, rule of law and freedom. From a social democratic perspective, it is essential to redefine resilience as the ability to withstand not only military threats, but also social, economic and environmental crises.
