ISLAMABAD — Vice President JD Vance, Special Envoy Steve Witkoff, and Senior Adviser Jared Kushner spent twenty-one hours in direct negotiation with Iranian Parliament Speaker Mohammad Bagher Ghalibaf and Foreign Minister Abbas Araghchi, mediated by the government of Pakistan. It was the highest-level face-to-face engagement between the United States and the Islamic Republic since the 1979 revolution, and the longest sustained diplomatic session of the current conflict.
No agreement was reached. The Vice President departed Islamabad having presented what he described as the United States’ “best and final offer.” The core demand — an affirmative, long-term commitment from Tehran not to pursue nuclear weapons or the tools to rapidly achieve them — was not met.
This newspaper exists to ask a single question of every development it covers: does this advance or protect the interests of the American people and their Republic? The answer this morning is more complex than the binary of deal or no deal suggests.
Consider what the United States accomplished by its presence in Islamabad. For nearly five decades, American diplomacy toward Iran has operated through intermediaries, back channels, and the blunt instrument of sanctions. The decision to send the Vice President — the second-highest constitutional officer of the United States — to sit across from senior Iranian leadership represents a strategic escalation of diplomacy that matches the military escalation that preceded it. The channel now exists. It did not exist six weeks ago. That channel is an American asset regardless of whether its first use produced a signed agreement.
Consider what the negotiating position revealed. The United States entered Islamabad with a demand that, if accepted, would constitute the most significant nonproliferation achievement since the dissolution of the Soviet Union. The administration has maintained that American and Israeli strikes have degraded Iran’s enrichment infrastructure at Fordo and Natanz — a position that, if validated, means Washington is negotiating from a posture of accomplished military objectives seeking diplomatic ratification, not from a posture of concession. The International Atomic Energy Agency has not independently confirmed the full extent of the damage, but the Iranian delegation’s unwillingness to commit to permanent denuclearization suggests that Tehran itself does not regard the matter as settled. That ambiguity is instructive: it tells Washington precisely where the pressure must be sustained.
Consider what Pakistan’s role portends. Islamabad’s emergence as a mediator — a nation that was regarded as a diplomatic outlier barely a year ago now hosting the most consequential trilateral negotiation of the decade — restructures the regional diplomatic geometry in ways that serve American interests. Pakistan shares a border with Iran. It maintains relationships with both the Gulf states and Tehran. Its government placed thousands of troops in the streets and converted the Jinnah Convention Center into a secure diplomatic venue. A Pakistan invested in mediating American-Iranian disputes is a Pakistan aligned with the resolution framework the United States prefers to the alternative: a region that resolves its disputes without American participation.
These are strategic gains. They are also, by themselves, insufficient. A diplomatic channel does not lower the price of gasoline. A clarified negotiating position does not reopen a shipping lane. And a new regional mediator does not bring home a single American service member deployed in the Persian Gulf.
The Strait of Hormuz remains functionally closed. Approximately twenty percent of the world’s petroleum transits that waterway, and every day it remains obstructed imposes costs on the American economy and on every allied nation whose energy security depends on Gulf supply lines. Iran’s Foreign Ministry has stated that the Strait’s status will not change until Washington accepts terms Tehran considers reasonable. The two-week ceasefire, while still nominally in effect, now operates without the diplomatic momentum that was supposed to carry it toward a permanent resolution.
The path forward demands clarity on three questions that the Republic’s elected representatives must now confront.
First, the question of authorization. The conflict with Iran is now in its seventh week. American forces are engaged in sustained combat operations in the Persian Gulf and have conducted strikes on sovereign Iranian territory. The Constitution vests the power to declare war in Congress. The longer the conflict continues without a vote of authorization, the weaker the institutional foundation upon which American policy rests — and the stronger the argument Tehran can make to the international community that the United States is operating outside its own constitutional framework.
Second, the question of verification. If American strikes have destroyed Iran’s enrichment capacity, the United States should welcome independent IAEA inspection to confirm what has been achieved. Verified destruction is a stronger negotiating position than claimed destruction. It converts a military assertion into a diplomatic fact, and diplomatic facts are the currency in which lasting agreements are denominated.
Third, the question of endstate. The American people are entitled to know what conclusion their government seeks — and that conclusion cannot be confined to the bilateral relationship with Tehran. Israel’s continued campaign against Hezbollah in Lebanon, which the Netanyahu government has declared is not covered by the Iran ceasefire, means that the broader regional war continues even if the bilateral conflict pauses. A durable American endstate requires a synchronized resolution across the theater: Iran, Lebanon, and the Strait. A ceasefire with the patron that permits continued hostilities against the proxy is a ceasefire whose architecture will not hold. The administration’s next diplomatic framework must be comprehensive enough to encompass the full scope of the conflict it initiated, or it will negotiate the same war in successive rooms without ever reaching its conclusion.
Twenty-one hours in Islamabad did not end the war. But they established that the United States and Iran can occupy the same room, negotiate in sustained session, and emerge with positions clarified rather than hardened beyond recovery. The American proposal now serves as the baseline for the next round of engagement — and there must be a next round. Pakistan remains willing to host. The diplomatic architecture built this weekend, however incomplete, is the foundation upon which the next attempt will stand.
The Republic’s task now is to ensure that the next session is entered with the full weight of constitutional authority, verified intelligence, and a negotiating framework broad enough to resolve not merely the nuclear question but the regional conflict it has become. That is how a Republic wages peace. That is how a Republic protects its interests. That is how a Republic wins.
