Donald Trump

Trump personally green-lit a strike on Iran for 2 August, having posted on Truth Social hours earlier that he would deploy force unmatched since the Second World War. He rescinded the order after Saudi Crown Prince Mohammed bin Salman warned that Gulf States, not Iran alone, would absorb any retaliation, with Qatar and the United Arab Emirates backing the same warning . It is the first halt credited to a named foreign leader rather than his own commanders or Congress.

The reversal fits the wider pattern of his Iran Conduct: threaten hard, order rarely, sign nothing. Even as CENTCOM disclosed its first boardings of the Hormuz blockade on 3 August, Trump was warning Iran it would be hit hard if the strait did not reopen, a promise still resting on rhetoric rather than a signed order .

Congress's attempts to compel Trump to end the Iran war keep failing on party lines. The House passed a non-binding withdrawal demand 214-208 on 23 July, but the Senate killed the binding measure that would actually have constrained him hours later, 47-49 . Only four House Republicans and one senator, Susan Collins, crossed over.

For Trump the defeat cost him nothing: the defectors were the same small bloc he had already written off weeks earlier, when he warned dissenters they 'have to be educated'. It is the latest of several War Powers deadlines his allies have run out the clock on, leaving him free to keep the campaign running on his own schedule rather than Congress's.

Even as Trump has escalated the air campaign, from strikes on Iran's nuclear sites to a bombing run that continued nearly nightly through mid-July, he has consistently ruled out sending US ground troops into Iran. That restraint has held even as the Pentagon's own cost accounting mounted: Defense Secretary Hegseth priced the war at $37.5 billion on 21 July, with no breakdown of obligated or appropriated spending .

It is the one consistent limit in a war otherwise defined by his shifting rhetoric on strikes, ceasefires and deadlines: threats of force 'unmatched since World War II' and a floated Hormuz toll have both come and gone, but the ground-troops line has not moved.
