The Pentagon has reportedly considered suspending Spain from NATO as part of a list of potential measures against allies seen as uncooperative during the conflict with Iran.

According to a report by Reuters, the idea appears in an internal email circulating at senior levels within the US Department of Defence (or Department of War).

The document outlines possible responses to allies that, in Washington’s view, did not back the US position during the war.

Spain among countries under scrutiny

One of the options mentioned is the suspension of Spain from NATO, in a move described as having limited military impact but significant symbolic consequences.

The same internal discussion reportedly includes other pressure tactics, such as blocking certain countries from key NATO roles and reconsidering US diplomatic positions on territorial disputes, including the Falkland Islands.

This could also cover Ceuta and Melilla, the two north African enclaves belonging to Spain.

No clear legal path

However, any such move would face a major legal hurdle.

NATO’s founding treaty does not include any mechanism to suspend or expel a member state. The only provision is voluntary withdrawal under Article 13.

That makes the idea, at least for now, more of a political signal than a practical step.

Spain plays it down

Pedro Sanchez, meanwhile, dismissed the report, saying his government does not act on internal emails but on official positions from Washington.

He reaffirmed Spain’s commitment to its allies, while stressing that cooperation must remain within the framework of international law.

Tensions have been building

Relations between Madrid and Washington have been strained in recent months.

US President Donald Trump has previously criticised Spain over defence spending and even suggested expulsion from NATO last year.

The divide has widened further over the Iran conflict, with Spain opposing parts of the US-led military strategy and refusing to allow American forces to use its bases for certain operations.
