The clock that was ticking toward a dramatic new escalation in the Iran war may now be counting down to a deal that would end it.

That’s the latest stunning turn of events delivered by President Donald Trump’s social media account.

Trump announced Monday that he was postponing his threatened military strikes against Iranian power plants for at least five days, hours ahead of his deadline for Tehran to reopen the crucial Strait of Hormuz shipping route.

He said the U.S. and Iran were in “productive” talks toward a “complete and total” resolution of the war, though Tehran denied any direct talks.

Trump’s reversal delays what many feared would be a significant new escalation for civilians across the region.

Iran’s Foreign Affairs Ministry appeared to counter Trump’s version of events, though, saying in a statement published by the semiofficial news agency Mehr News that there was “no dialogue between Tehran and Washington.”

It said Trump’s delay was “part of efforts to reduce energy prices and buy time to implement his military plans” but acknowledged “there are initiatives from regional countries to reduce tensions.” Iranian state media said Trump had “backed down” after Iran vowed swift retaliation for any attacks on its energy infrastructure.
