Tensions between the United States and Iran have intensified, with uncertainty surrounding upcoming negotiations. Following Iran's failure to respond, Vice President JD Vance's visit to Islamabad has been postponed. President Donald Trump announced an extension of the ceasefire and the continuation of the blockade against Iran until Tehran proposes a peace plan. A US delegation, expected to include Middle East envoy Steve Witkoff and senior adviser Jared Kushner, is anticipated to travel to Pakistan for discussions aimed at resolving the conflict, which has caused instability in the region and affected global markets. The situation escalated after the US Navy seized an Iranian cargo vessel near the Strait of Hormuz, an action Iran condemned as piracy. Trump has expressed mixed signals, oscillating between optimism for a deal and warnings of potential escalation, with the ceasefire set to expire soon, adding to the unpredictability of the situation.
