If U.S. President Donald Trump ends the war with Iran without a deal, he risks leaving Tehran with a stranglehold over Middle East energy supplies and Gulf Arab oil and gas producers grappling with the fallout of a conflict they did not start or shape.

Instead of crushing Iran¡¯s theocratic rulers, it could leave them stronger, emboldened by surviving weeks of U.S.-Israeli attacks, firing on Arab Gulf states and rattling global energy markets by effectively shutting the Strait of Hormuz.

In an interview before a scheduled address to the nation on Wednesday, Trump said the United States would end its war on Iran ¡°pretty quickly¡± and signaled on Tuesday he could wind down the war even without a deal.
