US Secretary of State Marco Rubio has said Washington may need to “reassess” its relationship with NATO after the ongoing Iran conflict, raising fresh concerns about strains within the alliance.
Speaking to Fox News on Tuesday, Rubio said the United States would have to take “a fresh look” at NATO’s value once the conflict ends, adding that the final decision would rest with President Donald Trump.
While describing himself as a long-time supporter of NATO during his time in the Senate, Rubio signalled growing frustration within Washington. “If we’ve reached a point where NATO means we can’t use those bases to defend America’s interests, then it becomes a one-way street,” he said.
He clarified that the US is not asking allies to participate in airstrikes against Iran but expects cooperation in allowing access to military bases. “If the answer is no when we need that access, then it raises serious questions about the purpose of the alliance,” he added.
The remarks come amid escalating tensions following the Iran conflict, particularly over access to strategic infrastructure. The Strait of Hormuz—through which nearly 20% of the world’s crude oil passes—has become a key flashpoint after Iran restricted movement in response to recent US-Israeli strikes.
Several NATO members have shown reluctance to support US operations. Spain has denied American aircraft access to its airspace, while Italy has refused landing permissions for US bombers. The United Kingdom had initially withheld access to a Royal Air Force base before later reversing its stance.
Rubio’s comments reflect broader disagreements within NATO over burden-sharing and strategic priorities, with the alliance facing renewed scrutiny as geopolitical tensions intensify.
