US Senator Marco Rubio commented on the uncertainty surrounding Iran’s leadership if Supreme Leader Ayatollah Ali Khamenei were to lose power. Speaking in the Senate shortly after President Donald Trump issued a new warning to Tehran, Rubio said it was unclear who would lead Iran in such a scenario. He cautioned that any forced regime change in Iran would be far more complex than the situation in Venezuela and noted that the aftermath of a government collapse would not have simple answers.

Rubio also mentioned that the United States might take preemptive defensive measures to protect its troops and allied facilities in the region if necessary, though he expressed hope that such a situation could be avoided. Meanwhile, Trump announced on social media that a large naval fleet was moving toward Iran and urged Tehran to return to negotiations to halt nuclear weapons development.

Iran rejected the US warnings, with Foreign Minister Abbas Araghchi stating that no talks could occur under threats and warning of an immediate and strong response to any military action. Both sides have maintained their positions, with Washington seeking a nuclear deal and Tehran insisting on continuing peaceful nuclear activities.
