US Secretary of State Marco Rubio expressed strong opposition to any tolling system that Iran might implement in the Strait of Hormuz, declaring it unacceptable and a significant threat to global diplomacy. During a press briefing, he emphasized that such a system would make any diplomatic agreement between the US and Iran unfeasible, calling it completely illegal. Despite these concerns, Rubio noted that there has been some progress in negotiations aimed at resolving the ongoing tensions related to the US-Israeli conflict with Iran. He acknowledged the complexities of dealing with a 'fractured' Iranian system, while also conveying a cautious optimism about the potential for a diplomatic resolution. 'There are some good signs,' Rubio stated, though he refrained from making any definitive predictions about the outcome. He also hinted that if negotiations do not yield results, President Trump has alternative strategies available, although he did not elaborate on what those might be. The situation remains fluid, with Rubio urging vigilance in the coming days as talks continue.
