U.S. Vice President JD Vance is poised to take on his biggest role yet on the international stage as President Donald Trump¡¯s chief negotiator to end the three-month war with Iran, a moment that could shape Vance¡¯s prospects as a White House successor.

The two nations agreed to a provisional peace agreement on Wednesday that suspended hostilities but left core issues unresolved, deferring decisions on Iran¡¯s nuclear program, its support for regional armed proxies and the economically vital Strait of Hormuz to 60 days of talks.

The discussions are a high-risk scenario for ?all sides in the conflict, the broader Middle East, and for Vance¡¯s political ambitions. And the situation remains fluid: Vance cancelled a planned Thursday night flight to Switzerland for the start of talks, ?though the ?White House said the U.S. delegation is ¡°prepared to depart at the first available opportunity.¡±
