A leaked internal Pentagon email has reportedly outlined a series of possible measures aimed at NATO allies over growing disagreements tied to the ongoing war with Iran, according to information obtained by Reuters.
The email, which is said to be circulating at senior levels within the Pentagon, reportedly explores ways the United States could respond to allies it believes have been reluctant to support American military operations.
Among the ideas mentioned are the possibility of suspending Spain from NATO roles and reviewing Washington’s position on Britain’s sovereignty over the Falkland Islands.
The proposals are understood to stem from frustration over what U.S. officials describe as limited access, basing, and overflight rights from some European allies during the Iran conflict.
One official said the email argued that such cooperation should be considered a basic requirement for NATO membership.
However, NATO has pushed back on the idea, noting that its founding treaty does not provide any mechanism for suspending member states.
The discussion comes amid broader tension between Washington and several European capitals.
President Donald Trump has repeatedly criticised NATO allies for what he sees as inadequate support in the Iran war, particularly around naval operations linked to the Strait of Hormuz.
He has also suggested the U.S. could reconsider its commitment to the alliance.
While the Pentagon declined to confirm the details of the email, a spokesperson said the administration is focused on ensuring the president has “credible options” as part of ongoing internal discussions.
Spain, which was mentioned in the reported email, has rejected the suggestion of any suspension.
Prime Minister Pedro Sánchez said Spain remains a committed NATO partner and does not respond to internal U.S. deliberations.
The memo also reportedly references broader geopolitical considerations, including reassessing U.S. diplomatic positions on long-standing territorial disputes such as the Falkland Islands, currently administered by the United Kingdom but claimed by Argentina.
Experts say the developments reflect growing pressure within NATO as the Iran conflict tests the limits of cooperation between the United States and its European allies.
