Middle East Conflict: Which Countries Restrict U.S. Military Aircraft Access?

Several European and neutral states have denied overflight and base access to U.S. aircraft taking part in operations against Iran. These measures followed the start of hostilities on February 28 and triggered public criticism from former President Donald Trump.

Context

As the Middle East conflict unfolded, many partners re-examined transit rules for foreign military flights. Governments faced questions over which countries restrict U.S. military aircraft access and on what legal grounds.

Country responses

France

Paris says it was not consulted and is not participating in the offensive. France has not altered its transit rules since February 28. Fighter jets carrying military cargo are barred, while tankers and logistics planes may operate from Istres.

Spain

On March 30, Madrid announced it would close Spanish airspace to U.S. planes involved in the conflict. Defense Minister Margarita Robles said U.S. bases in Spain were not available for those operations. Spanish press reported an emergency exception, but the government did not formally confirm it.

Austria

Vienna told AFP on April 2 that it refused all Washington requests for overflight from the start. Officials cited Austria’s declared neutrality in their decision. Austria has held neutral status since 1955.

Switzerland

On March 14, Bern invoked its neutrality and rejected two requests linked to the Iran conflict. The requests concerned reconnaissance flights scheduled for March 15. Swiss rules permit humanitarian, medical, and unrelated maintenance flights despite the ban; Switzerland’s neutrality dates to 1815.

Italy

Rome denied permission for U.S. aircraft to land at the Sigonella base in Sicily. The planes were reportedly already airborne, and there was no time to consult Parliament. Italy allows some U.S. logistical use of bases, but combat missions require government approval and parliamentary consent.

Implications

These decisions highlight growing friction among allies over military deployments. Restrictions that restrict U.S. military aircraft access complicate logistics for operations in the region.
