The rejection comes as Iran keeps pushing diplomacy as the only path out of its conflict with the United States. Iran's foreign minister, Abbas Araghchi, is waiting on a response from mediators about the strait rather than reacting directly to Trump's comments, according to Al Jazeera.

Iranian President Masoud Pezeshkian has said Iran "no longer trusts talks with Washington," a sign of how far apart the two sides remain even as Tehran floats a timeline to reopen the strait. A separate US official has claimed Trump holds all the cards in the negotiations, but Trump's public dismissal of Iran's seven-day offer suggests Washington sees little urgency to close the gap.

The strait matters far beyond the two countries fighting over it. It's a narrow passage that a huge share of the world's oil traffic depends on, and any extended closure or threat to it ripples through global energy markets.

Trump says Iran is negotiating from weakness, while Iran insists it doesn't trust the people across the table. What happens next remains unclear.
