US Threatens to Suspend Spain from NATO Over Iran War Support; Alliance Says 'No Provision' for Expulsion

Reports citing an internal Pentagon email have revealed that the United States is considering options to suspend or punish Spain over what Washington perceives as insufficient support for the Iran war effort. NATO swiftly responded, stating that the alliance has "no provision" for expelling member states — but the incident laid bare a deepening rift between the US and its European allies.

European NATO members pushed back sharply. BBC Europe editor Katya Adler described the situation as a "Medusa-like" dilemma for allies navigating the dual demands of alliance solidarity and not alienating Washington. Meanwhile, EU leaders are reportedly working on a new mutual defense pact to strengthen the bloc's collective security commitments independent of US leadership.

The episode reflects a broader friction in transatlantic relations: European governments have been more cautious in their support for military action against Iran, and Trump's administration has shown a willingness to use alliance membership as political leverage. For countries in the South Caucasus and Central Asia that rely on implicit Western security guarantees, growing uncertainty about NATO's coherence adds yet another layer of strategic complexity to an already volatile regional environment.
