Pakistani Prime Minister Shehbaz Sharif declared Saturday that the United States and Iran are "closer to a peace deal than ever before" and that his government expects a memorandum of understanding to be finalized within 24 hours. If true, the agreement would mark the most significant diplomatic breakthrough between Washington and Tehran in decades, and a vindication of the Trump administration's pressure-first, negotiate-second approach to the Islamic Republic.

But the deal is not done. A senior Trump administration official put the odds of a signed agreement at roughly 80 to 85 percent, up from 75 percent earlier in the day Friday, while cautioning that Iran's internal politics remain "very complicated." Iran's own Foreign Ministry spokesperson, Esmaeil Baghaei, told state media the signing would "not be tomorrow" and warned that "the hesitation of the other side" demands caution.

The gap between Sharif's optimism and Tehran's hedging tells a familiar story: when the United States negotiates from strength, the other side shows up at the table, but closing the deal requires watching what they do, not just what they say.

What we know about the proposed deal

The broad outlines, as described by the senior Trump administration official who spoke to reporters on condition of anonymity Friday, are sweeping. CNBC reported the possible memorandum of understanding would include reopening the Strait of Hormuz, steps to dismantle Iran's nuclear program, an end to Iran's funding of violence abroad, and the imposition of what the official called "an inspection regime."

In exchange, Iran would receive what the official described as "significant" economic relief, including the easing of long-term sanctions and the unfreezing of Iranian assets. The official was careful to add that those benefits would "only accrue if they actually deliver."

That conditional language matters. Previous administrations, most notably the Obama-Biden team behind the 2015 JCPOA, front-loaded economic concessions and hoped compliance would follow. The Trump administration appears to be structuring this deal the other way around: Iran moves first, and relief follows performance.

The official also said the memorandum "guarantees a long-term peace in the region" by ending Iran's sponsorship of proxy violence. Whether any piece of paper can guarantee that from a regime with Tehran's track record is the question every serious observer will ask.

Pakistan's role as mediator

Sharif, who has positioned Pakistan as a mediator between Washington and Tehran, posted on X that a "final, agreed upon text" had been reached and that Islamabad "is now working closely with both sides to finalize the next steps." He added that Pakistan was preparing for an electronic signing immediately after finalization, with technical-level talks to follow next week.

"With finalisation likely expected in the next 24 hours, Pakistan is preparing for the electronic signing of the peace deal immediately after, followed by technical level talks next week."

Trump reposted Sharif's remarks on Truth Social later Saturday without adding comment. The repost itself signals that the White House sees Sharif's framing as at least directionally accurate, or at minimum useful.

Pakistan's involvement as a go-between is worth noting. Islamabad shares a border with Iran, maintains working relationships with both sides, and has its own strategic reasons for wanting a stable settlement. Whether Pakistan's mediation role gives it undue influence over the terms, or whether it simply provides a convenient channel, remains an open question. In a region where the Trump administration has demonstrated it will use every available lever, the internal dynamics of the White House's approach to Iran have drawn their own share of public attention.

Iran's mixed signals

Tehran's public posture has been characteristically two-faced. Iranian Foreign Minister Abbas Araghchi wrote on X before Sharif's Saturday post that a memorandum of understanding "has never been closer." That tracks with Sharif's optimism.

But Baghaei, the Foreign Ministry spokesperson, struck a different note when quoted by Iranian state media. He said the exact signing date remained uncertain and pointedly blamed "the hesitation of the other side", meaning the United States, for the ambiguity.

"The possibility of this happening in the coming days cannot be ruled out. However, due to the hesitation of the other side, we must be cautious in making any comments about this process."

That framing, casting Washington as the reluctant party, is classic Iranian negotiating theater. The senior Trump administration official's own assessment that the regime has "internal fractures" suggests the real hesitation may be inside Tehran, not the Oval Office.

Iran's Mehr News Agency reported 14 purported provisions in the draft deal, including U.S. commitments to lift oil sanctions, end its naval blockade, and release Iran's frozen funds. Trump pushed back on those reports Friday morning on Truth Social, writing that public reporting about the deal has "NOTHING to do with the terms that were agreed to, in writing."

That flat denial raises the possibility that Iran's state-linked media is leaking a version of the deal designed for domestic consumption, one that makes the regime look like it extracted maximum concessions. It would not be the first time Tehran played that game. The question is whether the actual text, once public, matches Washington's description or Tehran's.

Israel's posture and regional stakes

Israeli Defense Minister Israel Katz made clear Friday morning that Tel Aviv will not withdraw its forces from Lebanon, Syria, Gaza, or a northern area of the West Bank. The timing of that statement, landing the same day as the deal's most optimistic signals, was not accidental.

The senior Trump administration official addressed the regional dynamic directly, saying the U.S. does not "expect any country, whether [in] the Gulf Coast or Israel, to give up their right of self-defense." But the official added an expectation that if all parties participate in the peace process, "everyone else will do the same." That language leaves room for Israel and Gulf states to maintain their security postures while still engaging with whatever framework emerges. It also leaves room for friction if Tehran interprets the deal as requiring Israeli concessions that Jerusalem has no intention of making.

The administration's challenge is clear: any deal with Iran that fails to account for Israel's security needs will face fierce opposition from Congress, from the Israeli government, and from the broader conservative coalition that has long viewed Tehran as the primary destabilizing force in the Middle East. Enforcement actions by federal agencies on other fronts, including recent large-scale visa fraud crackdowns, show the administration is willing to use institutional muscle when it matters. The same standard should apply to any inspection regime imposed on Iran.

What remains unclear

The full text of the memorandum of understanding has not been released. The signing location has not been determined. The identity of the senior Trump administration official who briefed reporters has not been disclosed. And the 14 provisions reported by Mehr News Agency have been directly disputed by the president himself.

The senior official's confidence estimate, rising from 75 percent to 80 or 85 percent over the course of Friday, but explicitly "not 100%", suggests that real sticking points remain. The official acknowledged that "we see issues pop up" and that the process is fluid. None of this is unusual in high-stakes diplomacy, but it does mean the celebratory framing from Islamabad may be premature.

Trump's Thursday remarks from the Oval Office, that the U.S. had "just made a great settlement of the war with Iran," pending "finalization of documents", set a confident tone. Whether that confidence is justified will depend entirely on the final terms and, more importantly, on whether Iran actually complies. Past experience with the regime offers little reason for optimism on that front. The broader political environment in Washington, where questions about institutional credibility and partisan misuse of federal power remain very much alive, means any deal will face intense scrutiny from all sides.

The bottom line

If this deal holds, it would represent a genuine achievement: a negotiated framework that addresses Iran's nuclear ambitions, its proxy warfare, and the Strait of Hormuz chokepoint, all without the front-loaded concessions that defined the Obama-era JCPOA. The structure, compliance first, relief second, inspections throughout, is the right architecture.

But architecture is not a building. The Trump administration has earned the right to negotiate from strength. It has not yet earned the right to declare victory. The deal's value will be measured not by the signing ceremony, not by Sharif's enthusiastic posts, and not by Araghchi's carefully hedged optimism. It will be measured by what Iran does after the ink dries.

Trust Tehran when it dismantles. Not before.
