President Donald Trump announced on Saturday that the United States and Iran would sign a peace deal on Sunday, citing a post on social media and declaring the war “essentially over.” Iranian officials responded with immediate ambiguity: the deal would come, they said, but not tomorrow. Simultaneously, explosions shook southern Lebanon as Israel pressed its military campaign against Hezbollah targets even as a ceasefire framework was supposedly being inked. The Strait of Hormuz, closed since the war’s opening weeks, remains the economic chokepoint hanging over the talks. A deal of any kind — even a preliminary one — would represent a significant achievement. But the gap between what Trump announced and what Tehran confirmed suggests the process remains fragile.
The received wisdom
The mainstream framing of this moment is straightforwardly celebratory: after months of a devastating, economy-rattling conflict that sent energy prices soaring and rattled allies from London to Tokyo, a negotiated end is precisely what the international order needs. The Biden-era foreign policy establishment, largely marginalised since January 2025, would say this vindicates engagement over maximalist pressure — that Trump stumbled into a deal that cooler heads had long said was achievable. Commentators at leading outlets are noting that both sides have indicated a deal is close and that the economic pressure, particularly the blockade of Iranian ports enforced by US naval assets, ultimately brought Tehran to the table. The progressive reading adds a humanitarian dimension: the war has killed thousands, displaced hundreds of thousands more, and the sooner it ends, the better, regardless of the process’s messiness.
That reading isn’t wrong. It’s just incomplete.
A different read
The gap between Trump’s Sunday announcement and Tehran’s “not tomorrow” response is more than a scheduling dispute. It is a window into the structural problems of personalised, presidentialist diplomacy — a mode of foreign policy making that produces dramatic announcements but sometimes struggles to deliver durable agreements.
History offers a useful caution here. Richard Nixon’s “peace is at hand” statement in October 1972, made days before a presidential election, was followed by two more months of brutal bombing before the Paris Accords were signed in January 1973. The announcement served a domestic political purpose — and the gap between proclamation and reality nearly unravelled the deal entirely. Trump’s Sunday deadline has a similar feel: a declaration timed to generate maximum political benefit, made before the text has been agreed and before the parties have converged on implementation.
What makes this particular negotiation more complicated than even the standard diplomatic haggle is the triangular nature of the conflict. The US-Iran dimension is only one axis. Israel’s continued strikes on Lebanon while Washington claims peace is at hand illustrates the degree to which an American president cannot simply declare an end to a war that involves an ally acting on its own strategic calculus. Netanyahu’s government has its own reasons for continuing military pressure — a ceasefire that leaves Hezbollah intact and Iranian influence in Lebanon unaddressed is not a ceasefire that serves Israeli strategic interests, whatever Trump announces from Washington.
Then there is the question of the Strait of Hormuz. Trump indicated it would reopen “shortly after” a deal is signed. But the chaotic talks have produced divergent public accounts from both sides about what was actually agreed. The Iranians have their own domestic political constraints: the memory of earlier bloody conflict looms large in Tehran’s political culture, and any deal that looks like capitulation under military duress faces intense internal opposition. Iranian public opinion is itself divided — some Iranians have responded with cautious optimism to news of a deal, others with scepticism.
The risk of Trump’s approach is that by front-running the announcement, he has given Iranian hardliners a domestic gift: they can now characterise any deal as a capitulation wrung out of Tehran by American bullying, while simultaneously holding out for better terms behind the scenes. Deals that begin with one side claiming total victory tend to have short shelf lives.
That said, there is a more charitable reading of what Trump is doing. Presidential announcements in advance of a deal being fully signed can serve as a form of political commitment device — making it harder for either side to walk away because the leader has publicly staked his reputation on closure. Kissinger used similar tactics. The question is whether Trump has the patience and the detailed knowledge of the negotiating text to hold the line if Tehran tries to renegotiate in the final hours. His record on that — from NAFTA to various aborted trade agreements — is mixed.
The BBC analysis notes that what appears to be flip-flopping from Trump may actually be a negotiating strategy: keeping Iran uncertain about his next move. That is a plausible reading. But strategies that depend on controlled unpredictability require extraordinary coordination between a president and his diplomatic and military teams. Given the evident gap between Trump’s public announcements and where Tehran says the talks actually are, the coordination looks imperfect at best.
What to watch
- Whether any document is actually signed in the next 48-72 hours: If Sunday comes and goes without a signing, the credibility cost to US diplomacy is significant.
- The Hormuz timeline: A reopening of the strait would be the most concrete signal that something real has been achieved; continued closure after a “deal” would suggest the agreement is thinner than claimed.
- Israeli military tempo: If Israeli strikes on Lebanon continue or intensify after a supposed US-Iran agreement, it will signal that Washington’s ability to impose a regional settlement is more limited than the White House is presenting.
- Iranian hardliner reaction: Watch for statements from the IRGC and the Supreme Leader’s office — these will be more reliable indicators of whether a deal can hold than public statements from either government’s negotiating teams.
