Vance travels to Pakistan without Iran

Vice President JD Vance has traveled to Pakistan for a diplomatic mission, but the planned talks have been thrown into disarray by Iran's absence. The trip was intended for a second round of US-Iran negotiations, but Tehran has refused to participate. This leaves the US delegation in Islamabad with no counterpart to negotiate with, effectively stalling the diplomatic process. The development follows Iran's formal refusal to engage and the earlier cancellation of Vance's scheduled trip.
