Reuters: Iran Preparing to Formally Decline US Proposal; Doha Round 4 Suspended; Ghalibaf Warns Permanent Negotiations Halt If Lebanon Campaign Continues — Day 95

Reuters reported on June 2, 2026 (Day 95) that Iran was preparing to formally decline the current US MoU proposal, citing the Lebanon military campaign as an unacceptable precondition for continuing talks. Iran's Parliamentary Speaker and lead negotiator Mohammad Bagher Ghalibaf stated that Iran could permanently halt negotiations if Israel's Lebanon ground operations continue — going beyond the June 1 (Day 94) suspension announcement and framing a potential total diplomatic withdrawal. The scheduled June 2–3 Doha round 4 did not proceed as planned following Iran's June 1 suspension announcement. However, backchannel communications through Qatari intermediaries remained active: a regional source told CNN that as of June 2 negotiations were 'back on track' in some form hours after the formal suspension — suggesting Iran's suspension was partly a pressure tactic rather than a complete withdrawal. Iranian FM Araghchi's statement that the ceasefire 'applies across the region including Lebanon' was interpreted by analysts as leaving diplomatic room: if Trump could constrain the Lebanon front (which he attempted via the Netanyahu call and Beirut advance constraint), Iran's stated precondition could be addressed. The parallel diplomatic and escalatory signals from Tehran on Day 95 reflected the same split between Ghalibaf's hardline legislative-negotiating track and Araghchi's MFA diplomatic track that has characterized Iran's posture since Day 88. The outcome of the round 4 Doha session will effectively determine whether Iran accepts a revised US proposal or formally withdraws from the MoU framework.
