Summary

Portuguese prosecutors have opened an investigation into the legality of the United States' use of the Lajes Air Base during hostilities with Iran. The probe centers on whether Washington obtained the required Portuguese authorization for military operations, as peacetime agreements do not apply during active conflict. This legal challenge highlights potential friction in US-EU alliance cohesion regarding support for operations against Iran.
