US Secretary of State Marco Rubio urges the UK and other partners to develop contingency plans for the Strait of Hormuz amid concerns about potential Iranian measures, including refusing to relinquish control of the waterway and imposing tolls. According to reporting, Rubio emphasizes the need for an alternative approach if access to the strategic shipping route is disrupted. The coverage also notes that the UK is preparing a mission concept described as operating “when no one shooting,” suggesting planning for scenarios that are designed to avoid or manage escalation while still addressing security and maritime access risks. Together, the articles frame Rubio’s remarks as part of broader diplomatic and security coordination efforts, focused on reducing reliance on a single outcome and improving readiness for multiple contingencies involving Iran’s posture toward the strait. The reports do not specify new enforcement details, but they indicate that “plan B” would be considered if negotiations or existing arrangements do not lead to the expected outcome for free transit through the channel.
