Negotiations between the United States and Iran got off to a rough start yesterday in Switzerland. Responding to reports that Iran had closed the Strait of Hormuz again over continued fighting in Lebanon, President Trump warned on social media: “Iran must immediately stop their highly paid PROXIES in Lebanon from causing trouble. If they don’t, we’ll hit Iran very hard again, just like we did last week, only harder!!!” The Iranian delegation threatened to walk out over the president’s warning. But they stayed, and the talks continued.
