Israel Warns of Iran War Return as Tehran Hardens Position on Uranium Demands

Israeli Prime Minister Benjamin Netanyahu convened an emergency operational assessment with senior officials on Thursday evening, hours after Israeli military intelligence assessed that the conditions for renewed conflict with Iran were approaching. The narrow-format meeting, reported by Israel's Channel 13, came as Tehran hardened its public position on the central sticking point of the negotiations: its enriched uranium stockpile.

Israel's Channel 12 reported that Iran is refusing to move on any element of a potential agreement without the simultaneous lifting of the US naval blockade currently enforcing maximum pressure on Iranian oil exports. A senior source familiar with the negotiations described Tehran's posture as one of escalating desperation, telling Channel 12 that Iranian officials are "going crazy" under the weight of the sanctions regime and its economic consequences. The assessment marks a deterioration from signals as recently as late March, when diplomatic channels suggested Iranian intermediaries had shown flexibility on peripheral issues in exchange for partial sanctions relief.

The Non-Negotiable Line on Uranium

Israeli officials have consistently framed the uranium question as existential. According to Channel 12's reporting of the Israeli intelligence estimate, Tehran is not prepared to compromise on the removal of its enriched uranium stockpile or the cessation of further uranium enrichment — the two conditions Tel Aviv has demanded as a baseline for any durable agreement. Israel has long argued that any civilian nuclear programme compatible with the Non-Proliferation Treaty does not require the stock of 60-percent enriched uranium that Iran has accumulated since 2019, and that the existence of that material constitutes a near-term weapons capability regardless of stated intent.

The gap between those positions — a verifiable enrichment rollback versus a diplomatic freeze with existing stocks — has defined the negotiating impasse since indirect US-Iran talks restarted under Omani and Qatari mediation. Western diplomats have privately acknowledged that the enrichment question cannot be finessed without Iran accepting physical removal of material to a third-country storage arrangement, which Tehran has rejected as sovereignty-violating. That structural impasse appears to have deepened rather than narrowed in recent days.

Ghalibaf's Departure and Tehran's Internal Fracture

The resignation of Iranian Parliament speaker Mohammad Bagher-Ghalibaf from the Iranian negotiating team adds a further dimension of instability to the picture. Ghalibaf, a close associate of Supreme Leader Khamenei and a figure with institutional standing in the Islamic Republic's power structure, stepping away from the talks was characterised by Israeli Channel 12 as evidence of a severe crisis inside Iran's leadership. His departure removes a known institutional voice from the negotiating process at a moment when cohesion inside Tehran's decision-making apparatus is under significant strain.

Iran's nuclear programme has also advanced materially in the months since negotiations stalled. The International Atomic Energy Agency reported in February 2026 that Iran had accumulated enough 60-percent enriched material for multiple weapon cores if the political decision were made, and that access to inspect the sites in question remained restricted. Iranian officials have defended the programme as entirely peaceful, pointing to the fatwa against nuclear weapons issued by Khamenei in the early 2000s and arguing that Western proliferation concerns are a pretext for regime-change pressure.

American Constraints on Israeli Operations

The same Channel 12 dispatch that described Iran's hardening posture also noted a striking tension in current Israeli strategy: at the explicit request of the United States, Israel is maintaining a restrained posture in Lebanon, with the conflict there kept at low intensity. The US pressure to hold the Lebanon front is partly a function of broader regional de-escalation calculations, and partly an effort to prevent a two-front scenario that would complicate any military contingency planning against Iran.

That restraint, however, appears to apply only to Lebanon. Israeli Channel 12 separately reported that Israel is weighing the possibility of renewed fighting on both the Iranian and Lebanese fronts simultaneously — a framing that suggests Tel Aviv is no longer ruling out a multi-theatre operation. The mini-security cabinet, scheduled to convene at 20:00 local time on Thursday, will be the forum in which those options are formally assessed. The political weight of that decision — whether to move toward military action against Iranian nuclear infrastructure while also managing a Lebanon front — falls directly on the Netanyahu government, which has consistently used the threat of force as a negotiating lever while resisting international pressure to permanently foreclose that option.

The Forward Picture

The convergence of these signals — a hardening Iranian position on enrichment, an internal fracture in Tehran's negotiating team, and an Israeli assessment that conflict is approaching — places the diplomatic track under acute stress. The Biden administration, which has maintained the naval blockade as a pressure instrument while reportedly exploring partial sanctions relief in exchange for enrichment pauses, faces a narrowing window before Israeli military action becomes the only remaining option on the table. Regional allies, including the Gulf states, have privately urged both sides to avoid escalation, citing the economic disruption that a conflict would impose on already fragile post-pandemic recovery across the region.

What remains genuinely uncertain is whether Tehran's hardline posture reflects a calculated negotiating strategy — raising demands to improve its eventual bargaining position — or a genuine shift in direction driven by internal hardliners who view any compromise as capitulation. The resignation of Ghalibaf, if it reflects a purge of relative moderates from the talks process, would suggest the latter. If it is a tactical manoeuvre within a factional system, the pathway back to talks remains open. The sources consulted for this article do not establish which interpretation is correct, and the intelligence picture remains contested.

This publication's primary framing centred on the convergence of Iranian negotiating collapse and Israeli operational assessment — a structural analysis of why the diplomatic corridor is closing rather than a purely event-driven dispatch. Reuters's wire framing, by contrast, led with US pressure tactics and the naval blockade as the central instrument.
