The European Union does not have the authority to close NATO military bases, as NATO is a separate military alliance comprised of its member states. Decisions regarding NATO bases are made collectively by NATO member countries. While the EU and NATO cooperate on various security issues, any closure or restructuring of military bases would be based on the decisions of NATO and its member nations, not the EU.
