US President Donald Trump on Saturday said a deal with Iran is scheduled to be signed on Sunday, raising hopes of a formal end to months of conflict that disrupted oil shipments through the Strait of Hormuz and threatened to drag the Middle East into a wider war.In a post on his social media platform Truth Social, Trump said the Strait of Hormuz would be immediately "open to all" once the agreement is signed."...The Deal is scheduled to get signed tomorrow, and immediately after it is signed, the Hormuz Strait is OPEN TO ALL. Our relationship with Iran is a much different and better one than previous Administrations have had. Unlike Obama’s Hundreds of Billions of Dollars in payments to them, including 1.7 Billion Dollars in green, cold cash, no money will exchange hands. At the appropriate time, when all is calm, we will go in and get the Nuclear Dust, buried deep under the powerful sunken granite mountains, thanks to our beautiful B-2 Bombers and their brilliant pilots, and downblend and destroy it, whether in Iran, or the United States. We look forward to working with Iran, and the entire Middle East, long into the future. Hopefully, this process will all work out quickly, easily, and smoothly. If it doesn’t, we have the ultimate alternative, hopefully never to be used again!" he wrote.Also Read: Pakistan PM says US-Iran peace deal signing expected within 24 hoursThe comments came amid growing signs that negotiations between Washington and Tehran are nearing a breakthrough.
