Trump threatens US tolls on Hormuz strait if Iran talks fail US President Donald Trump warned Saturday that Washington could impose tolls on the vital Strait of Hormuz waterway if negotiators are unable to complete a deal to end the Iran war. There will be no tolls "unless they are imposed by and for the United States of America, should the deal not be completed, for services rendered as the Guardian Angel to the countries of the Middle East for purposes of both past, present, and future reimbursement of costs," Trump posted on Truth Social.
