Trump Sends Toughened Terms to Iran — State Dept Confirms 'Dialogue Continues' Despite Stalled MOU

On June 1, 2026, a US State Department official confirmed to NPR that back-channel dialogue with Iran was continuing even as the Trump administration dispatched significantly toughened demands to Tehran for the proposed Memorandum of Understanding. Trump's revised terms — reported by Fox News, The Hill, and Al Jazeera — went substantially beyond the tentative framework negotiating teams had agreed on May 28. The new US conditions included: stricter, more detailed nuclear language specifying exact timelines and verification mechanisms for enrichment suspension; explicit commitments on the transfer of Iran's 440.9 kg stockpile of 60%-enriched uranium to a third country before any major sanctions relief; additional guarantees on the Strait of Hormuz reopening with no preconditions, directly rejecting Iran's demand for IRGC escort fees; and language preventing Iran from maintaining any active enrichment cascade even at civilian-grade levels for a defined period. Iran's Foreign Minister Abbas Araghchi publicly stated that talks were 'proceeding' while insisting Iran had 'firm red lines' on enrichment rights and the release of frozen assets, and that the ceasefire extension was not contingent on the MOU being signed. Trump posted on Truth Social that 'Iran really wants to make a deal' — a signal that he viewed himself as negotiating from a position of strength. The White House indicated that a senior envoy would return to the Gulf for follow-on talks. Analysts noted the dynamic as consistent with Trump's transactional approach: tighten terms to demonstrate dominance before signing, forcing Iran to move toward the US position. With the April 8 ceasefire's 60-day extension expiring in mid-June, both sides faced a ticking clock.
