US and Iran fail to reach agreement on ending Middle East conflict

Vance, leading the US delegation, stated that the Iranian side did not accept American conditions. According to The New York Times, Vance expressed regret that the Iranians "chose not to accept our conditions." The Wall Street Journal reported that Vance specified Iran's refusal to commit to not developing nuclear weapons as the reason for his departure from negotiations.

However, Vance left open the possibility of a future agreement, stating, "We are leaving here with a very simple proposition: a basis for understanding that is our final and ultimate offer. We will see if the Iranians accept it." These negotiations, which continued until Sunday morning Pakistan time, marked the first high-level face-to-face meeting between US and Iranian officials since 1979.
