Vice-President J.D. Vance on 4 September declared that the United States will not enter negotiations with Iran until Tehran ceases its attacks on commercial shipping, warning that Washington holds a full spectrum of pressure tools — economic, military, diplomatic, and covert — to protect global energy supplies and prevent Iran from reconstituting its nuclear programme.

The Core US Condition

'The President's been very clear, we're not talking to them and we're not going to talk to them unless they stop shooting at commercial shipping,' Vance said at a White House press briefing. He declined to set any timeline for ending US operations, arguing that their duration depended entirely on Iran's conduct in the Strait of Hormuz. 'We're not going to set an artificial timeline,' he said, adding that disclosing a timetable while Iran continued threatening oil and gas vessels would be irresponsible.

Energy Flow and Military Posture

Vance pushed back against characterisations of the situation as an active war, insisting that major combat operations had ceased and that the immediate US objective was keeping energy corridors open. He cited a concrete figure to underscore the point: 15 million barrels of oil passed through the Strait of Hormuz the previous night, which he attributed directly to US intervention. 'The Iranians would like zero million barrels to come out of the Strait of Hormuz. Last night, 15 million barrels came out of the Strait of Hormuz,' he said. 'That's because of the United States of America.'

All Options on the Table

When asked whether the administration was considering arming Iranian dissidents, Vance declined to confirm or deny. He did, however, signal that President Donald Trump retained a broad range of options. 'Everything that could happen is on the table: Economic pressure, military pressure, diplomatic pressure, covert pressure,' he said. He also noted that the US had already destroyed Iran's nuclear enrichment capacity and was now focused on ensuring Tehran could not rebuild it.

China and Regional Partners Playing a Role

Vance said China had responded to some US requests regarding Iran, though he was uncertain whether Trump had spoken directly with Chinese President Xi Jinping about restricting financial services to Tehran. 'I think the Chinese, the PRC, being willing to play ball here,' he said, adding that Beijing had been 'much more responsible certainly than the Iranians,' even if it had not fulfilled every US ask. He also named Turkey, Azerbaijan, the United Arab Emirates, Saudi Arabia, and Qatar as countries applying pressure on Iran, with some cooperating privately without public acknowledgement.

Why the Strait of Hormuz Matters

The Strait of Hormuz is one of the world's most critical energy chokepoints, connecting Gulf oil-producing nations to international markets. Any sustained disruption risks spiking shipping costs, insurance premiums, and global crude prices — consequences that would ripple far beyond the Middle East and directly affect import-dependent economies including India. Vance argued that the absence of a global energy crisis at this juncture was itself evidence of US success in protecting the waterway, and that no other country possessed the capability to perform that role.
