Italian Defence Minister Guido Crosetto denied permission for U.S. military aircraft to land at the Sigonella air base in Sicily due to lack of prior formal authorization and consultation with Italian military leadership. The decision, affecting U.S. bombers en route to the Middle East, marks a violation of bilateral treaties governing American use of military installations in Italy. The flight plan was reportedly communicated while aircraft were already airborne, and checks indicated these were not routine logistical flights.
Italy becomes the second NATO ally in recent weeks to restrict U.S. military movements related to the Iran conflict. Spain earlier closed its airspace and denied base access to U.S. planes involved in operations against Tehran, underscoring growing European unease over involvement in the escalating Middle East confrontation. Prime Minister Giorgia Meloni's government maintains that Italian bases support logistical operations only, with combat-related activities requiring parliamentary approval.
Legal framework and domestic pressure
Italy's decision rests on specific treaty provisions governing foreign military use of Italian territory. Bilateral agreements require prior consultation and formal authorization for non-routine operations, particularly those involving combat-capable aircraft or missions related to active conflict zones. The U.S. flight plan, submitted after aircraft departure, failed to meet these procedural requirements.
Opposition parties in Italy have intensified pressure on the Meloni government to avoid entanglement in the U.S.-Iran conflict. The unauthorized nature of the flight request provided clear legal grounds for denial, allowing Rome to assert sovereignty without directly challenging broader alliance commitments. Italian officials emphasized the procedural violation rather than policy disagreement, though the timing amid the Iran war is not coincidental.

Historical precedent for Italian sovereignty assertion
The Sigonella air base has been the site of previous U.S.-Italian tensions over jurisdiction and authorization. In October 1985, Italian and American forces faced off at the same base when Italy refused to allow U.S. special operations forces to take custody of Palestinian hijackers. Italian Carabinieri surrounded U.S. personnel, ultimately asserting Italian sovereignty over events on Italian soil. The incident established a precedent for Rome's willingness to enforce its authority even when doing so directly contradicts American operational objectives.
The current denial operates in less dramatic but strategically similar terms. Italy is asserting that U.S. use of Italian bases must conform to established legal procedures and political oversight, regardless of operational urgency or alliance expectations. As the Iran conflict continues with no clear resolution, European governments are recalibrating their legal and political tolerance for serving as staging areas for American military operations in the region.
