Vice President JD Vance is warning Iran not to “play” the U.S. as he heads for negotiations aimed at ending their war. President Donald Trump has tasked the member of his inner circle who's seemed to be the most reluctant defender of the 6-week-old conflict to now find a resolution. Vance has long been skeptical of foreign military interventions. Trump notes Vance is “less enthusiastic” than other senior officials in his Republican administration. Vance set off Friday to lead mediated talks with Iran in Pakistan. Vance says he's “looking forward to the negotiation” and thinks it'll be positive. Vance's trip comes as a tenuous, temporary ceasefire appears to be on the precipice of collapsing.
