Vance to lead second Islamabad round as Khamenei approves delegation; Ghalibaf rejects talks under threat
Vice President JD Vance is scheduled to arrive in Islamabad Wednesday for a second round of Pakistan-mediated talks aimed at extending the Iran-US ceasefire, The Hill reported, citing White House preparations. Axios reported Tehran dispatched a delegation after Supreme Leader Ayatollah Ali Khamenei, through his son Mojtaba, authorized participation. Iranian parliament speaker Mohammad Bagher Ghalibaf said late Monday that Tehran will not negotiate "under the shadow of threats" and is prepared to "reveal new cards on the battlefield" if the ceasefire collapses. Business Upturn reported both delegations arrived simultaneously in Islamabad Tuesday morning. Iran previously denied it would attend.
Analysis
A deal by Wednesday's deadline is very unlikely within 48 hours. The likeliest near-term outcome is a short stop-the-clock extension that parks the ceasefire on a new calendar without resolving the 60% uranium question. The structurally decisive signal is Khamenei's authorization transmitted through his son Mojtaba, per a single Axios/CTK report not yet corroborated by US outlets, which outweighs any Araghchi or Gharibabadi statement because it locks Tehran into the Islamabad track regardless of Ghalibaf's "under threats" caveat. That parliamentary posture may be a domestic ceiling rather than a negotiating floor, with hardliner pressure absorbed at the speaker level while Araghchi negotiates in parallel. Vance arriving in person alongside Witkoff and Kushner, against the April 18 baseline of a Tehran shuttle without White House principals, raises the political cost of a US walkaway: Trump cannot default to the military option he has publicly floated without visibly overruling his own Vice President within the same window.
