Chicago – June 21, 2026
U.S. Vice President JD Vance landed Sunday in Switzerland to help formally launch negotiations with Iranian leaders over curbing Tehran’s nuclear program and building out the fragile interim deal to end the war in Iran.
The framework was signed last week, and now top U.S. and Iranian negotiators are in a 60-day sprint to reach an agreement on the technical details that hold massive implications for the world economy and global security.
Yet the first days of that two-month period were complicated by the heavy exchange of fire in Lebanon between Israel and the Iranian-backed militant group Hezbollah — and by the subsequent announcement by Iran’s military that it had closed the Strait of Hormuz, the vital waterway that transits a fifth of the world’s traded oil and natural gas.
Vance had originally been slated to be on the ground at the picturesque Bürgenstock resort near Lucerne on Friday, but his departure from the United States was delayed after fighting escalated in Lebanon and Iranian officials canceled plans to attend the talks.
