A major rift is emerging inside NATO as U.S. Secretary of State Marco Rubio blasted America’s allies for refusing to back Washington during the escalating Iran crisis. Speaking before the NATO Foreign Ministers’ meeting in Sweden, Rubio revealed that President Donald Trump was “very disappointed” with NATO countries that agreed Iran is a global threat but refused to take action. Rubio’s explosive remarks have fueled speculation that the Trump administration could be preparing unilateral moves against Iran as tensions in the Middle East continue to rise. The comments also expose deepening cracks inside NATO over military burden-sharing, the Strait of Hormuz crisis, and Europe’s reluctance to confront Tehran directly.
