An internal Pentagon email has outlined potential measures the United States could take against NATO allies it believes failed to support U.S. operations during the Iran war, a U.S. official told Reuters.
The options reportedly include suspending Spain from the alliance and reassessing Washington’s stance on Britain’s claim over the Falkland Islands.
Frustration Over Lack of Support
The proposals stem from frustration within the Pentagon over what it sees as reluctance among some allies to provide access, basing and overflight (ABO) rights during the conflict with Iran.
According to the official, the internal note described ABO support as “the absolute baseline for NATO,” with discussions taking place at senior levels within the Pentagon.
One proposal suggests sidelining “difficult” countries from key or prestigious NATO roles as a form of pressure.
Trump Criticism of Allies
Donald Trump has repeatedly criticised NATO allies for not deploying naval forces to help reopen the Strait of Hormuz, which was disrupted after the conflict began on February 28.
He has also raised the possibility of the U.S. withdrawing from NATO, though the internal email does not recommend such a move, the official said.
Europe Pushes Back
European allies, including Britain and France, have argued that joining U.S. naval operations during the conflict would have amounted to entering the war. However, they have indicated willingness to help secure maritime routes once a ceasefire is achieved.
Spain, in particular, has faced criticism after refusing to allow its bases and airspace to be used for offensive operations against Iran. The U.S. maintains key military installations there, including Naval Station Rota and Morón Air Base.
Responding to the report, Spanish Prime Minister Pedro Sánchez said Madrid does not act on internal communications but on official government positions.
Falklands Option Raises Stakes
Another option outlined in the memo involves reconsidering U.S. diplomatic backing for Britain’s claim over the Falkland Islands, which are also claimed by Argentina.
The islands were the focus of the Falklands War between Britain and Argentina, a conflict that continues to influence regional geopolitics.
Alliance Under Strain
The Iran war has exposed deep divisions within NATO, raising concerns about the alliance’s cohesion and future. Analysts warn that disagreements over military support could weaken collective security commitments.
U.S. officials have stressed that NATO cannot function as a “one-way street,” signalling a tougher stance toward allies perceived as not contributing equally.
Defense Secretary Pete Hegseth said the conflict had revealed critical gaps in alliance solidarity.
“You don’t have much of an alliance if countries are not willing to stand with you when you need them,” he said.
