TEHRAN, Iran — The diplomacy of smiles between the United States and Iran has come to an end. Not even regular old diplomacy seems to be an option anymore, with US President Donald Trump clearly stressing the importance of countering what he calls the Iranian regime's "destabilizing activity and support for terrorist proxies in the region.”
Trump took things back to square one, undoing the path that was paved during two years of marathon negotiations between diplomats and experts from Iran, the United States and the other world powers that negotiated the Joint Comprehensive Plan of Action in different venues around the world. The nuclear deal, struck in July 2015, was seen as a required step before there could be any cooperation between Tehran and Washington on regional crises, mainly Syria and Iraq.
