Trump Calls Off Witkoff and Kushner Pakistan Trip; Iran Nuclear Round 2 Collapses Before It Begins

On April 26, 2026, President Trump abruptly cancelled the planned trip of US Special Envoy Steve Witkoff and adviser Jared Kushner to Pakistan for a second round of Iran nuclear talks. Trump cited the length of the journey and characterized Iran's negotiating position as insufficient, stating the offer was 'not enough.' The cancellation came one day after Witkoff and Kushner had departed for Islamabad, with Iranian FM Abbas Araghchi already in the region meeting Pakistani officials. Araghchi responded by pressing on with a regional diplomatic tour — including stops in Oman and continued consultations with Pakistani PM Shehbaz Sharif — maintaining the back-channel architecture even as the formal US-Iran diplomatic track stalled. Iran's Foreign Ministry framed the collapse as confirmation that direct talks were never formally scheduled. The breakdown represents the second major rupture in the Islamabad format: Round 1 (April 11–12) collapsed after approximately 21 hours over uranium enrichment terms; the aborted Round 2 did not even produce a meeting. The structural divide remains: Washington demands a 20-year pause on Iranian uranium enrichment; Tehran has offered 5 years. The US naval blockade of Iranian ports and ongoing IRGC seizures of vessels in the Strait of Hormuz continue in parallel, complicating the diplomatic track. CNN reported that Araghchi continued regional consultations despite the US cancellation, preserving Iran's posture of conditional diplomatic engagement.
