WASHINGTON — A senior administration official said Friday that a deal with Iran to end the war and reopen the Strait of Hormuz could be signed within days, downplaying concerns that Tehran would reap immediate economic gains from the emerging agreement. “We're not quite at the finish line yet, but we are very close," the official said in a call with reporters. The official laid out the memorandum of understanding's terms, which include Iran reopening the Strait of Hormuz and the United States lifting its naval blockade. Tehran sought access to billions of dollars in frozen funds in exchange for signing the deal. “The Iranians don't get anything upon the signing of the MoU,” the official said. “Their benefits under the deal only come when they actually perform what they're supposed to perform.”The memorandum of understanding also includes a “commitment” from Iran to dismantle its nuclear weapons program and decommission its nuclear facilities, the official said. “They are committing indefinitely to not build or procure a nuclear weapon, and then we're going to have to figure out exactly how we enforce that,” the official said. This is a developing story and will be updated.
