Pentagon Mulls Sanctions on NATO Allies Over Iran Dealings

The United States Pentagon has held internal discussions about possible steps to penalize NATO allies it views as insufficiently supportive of U.S. operations in the ongoing conflict with Iran, according to a U.S. official who described the matter on April 24, 2026. The official said the ideas have circulated at senior levels inside the Pentagon. The deliberations were described as options rather than announced policy.

Among the measures referenced in an internal email are proposals to suspend Spain from the alliance and to revisit the U.S. position on Britain’s claim to the Falkland Islands. The email, as described by the official, conveyed frustration with some allies’ reluctance to provide access, basing, and overflight (ABO) rights connected to the Iran war. It characterized ABO permissions as the “absolute baseline for NATO.”

Spanish Prime Minister Pedro Sanchez responded by saying Spain operates on the basis of official documents, not emails. The internal message also framed the contemplated steps as a way to demonstrate U.S. dissatisfaction and to reduce what it called a “sense of entitlement” among European allies. The official said the email did not propose a U.S. exit from NATO or the shutdown of U.S. bases in Europe.

The same internal discussion outlined other potential actions, including suspending countries described as “difficult” from influential NATO roles. Pentagon Press Secretary Kingsley Wilson said the War Department is developing credible options for the President aimed at ensuring allies meet their commitments. No timeline for decisions was provided in the account, and it was not clear which allies, beyond Spain, were being considered for specific measures.

The developments come as the U.S.-Israeli conflict with Iran raises questions about the durability of NATO cohesion. NATO is 76 years old, and the internal debate described by the U.S. official highlights tensions over operational support, particularly the granting of access, basing, and overflight rights. The email’s language suggests that, at least within parts of the Pentagon, these permissions are being treated as a central test of alliance solidarity during the current conflict.

Key uncertainties remain. The internal email reflects discussions and proposals, but it does not establish that any action will be taken, nor does it indicate that the United States intends to leave NATO or close European bases. It is also unclear how allies would respond if such options were pursued, or how any changes in U.S. positions—such as on Britain’s claim to the Falkland Islands—would be implemented in practice.
