US-Iran conflict: A fragile calm or the beginning of diplomacy?

After nearly two weeks of heavy fighting between the US and Iran, the two sides have stopped striking each other, at least for now. US President Donald Trump says he has paused the attacks to give negotiations another chance, but Tehran denies that any direct talks are taking place. Meanwhile, Israeli Prime Minister Benjamin Netanyahu is in Washington for talks with President Trump, and the outcome could prove pivotal for the next phase of the crisis. Is the war in Iran moving toward diplomacy or another escalation? Can Washington and Tehran overcome their disputes over the Strait of Hormuz and the terms of a broader agreement? And could differences between Trump and Netanyahu determine whether the conflict moves toward diplomacy or renewed escalation?
