Tensions around Iran’s nuclear negotiations and the Strait of Hormuz intensify as Iran says it has closed the strategic waterway. Iran states the closure is linked to what it describes as Israel’s attacks in Lebanon, and it warns that if fighting does not stop, little progress is likely even as negotiators prepare to meet in Switzerland to discuss an interim agreement with the United States.

In response to the situation, U.S. President Donald Trump threatens to impose “U.S. tolls” on the Strait of Hormuz if a final Iran deal is not reached within 60 days. The warning underscores pressure on the negotiations, with both sides tying their next steps to broader regional hostilities.

The developments connect maritime security concerns to the status of U.S.-Iran talks, with Iran signaling that regional conflict could affect cooperation and the U.S. signaling that it may use economic and maritime leverage to push toward a final agreement.
