An internal Pentagon email is circulating at high levels outlining punishment options for NATO allies deemed to have failed Washington during the Iran war, a U.S. official told Reuters on April 24. The official described the contents on condition of anonymity. The options were described as being intended to send a strong signal rather than immediately alter military posture.

The email centres on allied failures to grant what the Pentagon terms ABO rights — access, basing and overflight — which the document reportedly frames as the absolute baseline of NATO membership. Countries identified as “difficult” in the note face a range of proposed consequences, from symbolic demotions within alliance structures to direct challenges to their territorial claims.

The note does not recommend withdrawing from NATO, and the official clarified that base closures in Europe are also not among the options listed. A widely anticipated US force drawdown from certain European countries was not confirmed as part of the email’s content, though the official declined to specifically rule it out.

Spain sits at the centre of Washington’s frustration. The socialist government in Madrid publicly declared it would not allow its territory or airspace to be used for offensive operations against Iran. That refusal put two strategically critical facilities directly in the spotlight: Naval Station Rota and Moron Air Base, both of which carry significant US operational weight in the Mediterranean and Atlantic approach.

The email proposes suspending Spain from prominent or prestigious NATO positions. The official who disclosed the contents acknowledged the practical military impact would be limited, but stressed the symbolic weight of such a move would be substantial. Washington appears to be calculating that prestige and standing matter to European governments in ways that direct military threats do not.

No mechanism for formally suspending a NATO member currently exists in the alliance’s founding treaty, and the official could not describe how such a step would be legally pursued. The option appears intended as political pressure rather than an immediately executable action.

The most striking option in the email targets Britain directly. The document reportedly includes a proposal to reassess longstanding US diplomatic support for European “imperial possessions” — with the Falkland Islands cited specifically. The islands are administered by the United Kingdom but formally claimed by Argentina, whose president Javier Milei has cultivated close ties with Trump.

Britain has drawn repeated public criticism from Trump during the Iran conflict. The president called Prime Minister Keir Starmer cowardly and dismissed British aircraft carriers as toys, after London initially declined US requests to use its bases for offensive Iran strikes. Britain later partially relented, permitting defensive missions to protect residents in the region.

The State Department’s official position currently acknowledges UK administration of the islands while noting Argentina’s unresolved claim. Shifting that language — or withdrawing it entirely — would be a significant diplomatic rupture with an ally Washington still technically classes as a close partner.

Defense Secretary Pete Hegseth set the tone for the email’s contents in remarks at the Pentagon earlier this month. He stated publicly that the Iran war had exposed deep fault lines within the alliance, noting that Iran’s longer-range missiles cannot reach the United States but can reach Europe. The implication was direct: European allies have more reason than America to support the campaign, yet many have refused.

Trump himself has repeatedly floated the prospect of a US withdrawal from NATO since the Iran war began. Asked by Reuters on April 1 whether leaving the alliance was a genuine possibility, he did not rule it out, replying only with a rhetorical question implying the answer was yes. The Pentagon email does not include withdrawal as an option, but the public statement from the president gives the implied threat significant weight.

Britain and France have both argued that joining the US naval blockade of the Strait of Hormuz would constitute active participation in the war, a step their governments have declined to take. Both have stated willingness to help reopen the strait once a lasting ceasefire is in place or the conflict concludes. Washington regards that condition as an unacceptable restraint on allied solidarity.

The European position reflects genuine domestic political constraints as well as legal concerns about collective defence obligations under Article 5. Joining a US offensive war is categorically different from responding to an attack on alliance territory. Most European capitals are navigating a situation where American expectations outpace the political consensus at home.

The standoff has created an unprecedented moment of open alliance fracture. American officials are discussing punishments publicly; European leaders are responding by pointing to legal frameworks rather than solidarity. Neither side appears to be moving toward the other.
