Truce without talks: What room for diplomacy between US and Iran?

How to mediate between Iran and the United States when one side wants revenge for the killing of its leader and the other’s erratic messaging seems ratings driven?Donald Trump’s unilateral ceasefire declaration bringing neither side back to the bargaining table, what with more ships seized in Strait of Hormuz and lockdown mode relaxed in Pakistan’s capital, this for talks that may or may not resume. We’ll ask about US demands that can change course inside the same presidential tweet…and an unclear chain of command on both sides: why was the US president flanked by Trump confidantes Jared Kushner and Steve Witkoff last time? Does it actually matter that none of those three are trained diplomats or Iran specialists?
