Scheduled peace talks between the United States and Iran have been cancelled, according to the Swiss Foreign Ministry. The cancellation follows an announcement from the White House that Vice President J.D. Vance would not attend the meeting. Earlier this week, both nations signed a letter of intent aimed at ending the ongoing conflict. President Donald Trump signed the agreement Wednesday in Versailles, with Iranian President Masoud Pezeshkian providing an electronic signature. The meeting in Switzerland was intended as a ceremonial signing of the accord, but will no longer take place. The reason for Vance’s withdrawal remains unclear, casting doubt on the future of the peace process.
