US President Donald Trump has expressed deep dissatisfaction with NATO members’ response to the ongoing military activities surrounding Iran, according to senior US diplomat Marco Rubio. Speaking to reporters, Rubio said frustration within the Trump administration over NATO’s stance is growing, particularly after Spain refused to allow the US to use its military bases. He noted that such cooperation is central to NATO’s purpose, enabling rapid military deployment in crisis regions like the Middle East.

Rubio questioned the logic of NATO membership for countries that restrict such cooperation, emphasizing that the alliance’s strength lies in shared military access and readiness. He added that NATO members’ support for US efforts related to the Iran conflict has been far below expectations, which has intensified Trump’s disappointment with the alliance.

The remarks highlight ongoing tensions between the Trump administration and NATO, continuing a pattern of US criticism over European allies’ defense spending and military collaboration.
