President Donald Trump and Vice President JD Vance are engaging in high-stakes negotiations with Iran in Islamabad to prevent the expiration of a fragile two-week ceasefire.The US demands that Iran relinquish its uranium stockpiles and cease efforts to control the strategic Strait of Hormuz to resolve a conflict that has caused a global energy crisis.These diplomatic efforts run parallel to US-led mediation between Israel and Lebanon, as military tensions persist following intercepted shipments and naval confrontations.International observers remain concerned that failure to reach a comprehensive agreement could lead to renewed military escalation throughout the Middle East.
