Permanent Structured Cooperation (PESCO) is a framework established by the European Union to enhance defense cooperation among member states. It allows countries to collaborate on military projects, improve their defense capabilities, and ensure a more coordinated response to security challenges. PESCO aims to foster deeper integration in defense by encouraging member states to invest in joint military initiatives and share resources. This cooperation helps to strengthen the EU's security and defense policy, making it more effective in addressing threats and promoting stability within and beyond Europe.
