The U.S.-Iran peace deal was dead before the ink dried — talks scheduled for Friday in Switzerland were scrapped after Iran refused to send its delegation while Israel keeps bombing Lebanon, leaving American diplomats on a tarmac and taxpayers footing the bill for a diplomatic exercise that never started.

On Wednesday, President Trump and Iranian President Masoud Pezeshkian signed a memorandum of understanding opening a 60-day window to negotiate a permanent agreement on Iran's nuclear program and end the war. The deal called for an immediate halt to military operations "on all fronts, including in Lebanon" and reopened the Strait of Hormuz, where roughly 80 mines had choked off oil shipments and sent prices skyrocketing. Trump said he signed to avoid "economic catastrophe" in the U.S., according to AP News.

By Friday, it was already falling apart. Iran didn't send its delegation to the Swiss resort of Burgenstock, citing Israel's ongoing military campaign in southern Lebanon. Hezbollah-linked Al-Mayadeen first reported Tehran was delaying over the strikes; Iran's semi-official Tasnim news agency added that negotiators needed signs of U.S. implementation before proceeding, Breitbart reported.

Vice President JD Vance was literally on the tarmac, ready to board, when the no-show was confirmed, per Breitbart. Dozens of diplomatic and security officials were already in Switzerland preparing for his arrival. The Swiss Foreign Ministry confirmed the postponement.

The fighting that sank the diplomacy was fierce. Israel struck more than 80 targets across southern Lebanon and the Bekaa Valley overnight, the Israeli military said. Lebanon's Health Ministry reported at least 18 killed. Four Israeli soldiers died when their tank was hit near Kfar Tebnit — one of the deadliest single strikes on Israeli forces since March, the New York Times reported. Hezbollah claimed it destroyed three Merkava tanks with guided missiles and ambushed Israeli troops near a strategic height in southern Lebanon.

The core problem: Israel is not a party to the deal, and Prime Minister Benjamin Netanyahu has made clear he is not bound by it. Netanyahu said Thursday that Israeli forces will remain in a "security zone" in southern Lebanon as long as "Israel's security needs require it," AP reported. He faces elections later this year. The interim deal doesn't explicitly require Israeli withdrawal from territory it occupies.

Trump has been openly critical. "Without the U.S. there would be no Israel," he said before signing. "Now Bibi has to be more responsible with respect to Lebanon." Vance issued an unusually sharp rebuke to Israeli critics: "Donald J Trump is the only head of state in the entire world who is sympathetic to the nation of Israel at this moment in time. If I was in the cabinet of the Israeli government, I might not be attacking the only powerful ally that I have anywhere left in the entire world." The New York Times noted that Vance relied on "vague and misleading claims" about Iran gaining little if it didn't comply with U.S. demands — and if the deal holds, billions in frozen Iranian assets would be released. Some Republicans in Congress and Israeli lawmakers have criticized the agreement for giving Iran economic relief while punting on the nuclear question.

But Ambassador Mike Huckabee split with the White House, posting on X: "Israel strikes when struck... Ceasefire happens when Hezbollah stops shooting & killing."

Follow the money: The Strait of Hormuz reopening got 12.5 million barrels of oil flowing again Wednesday night, per AP. Oil prices wavered as cracks emerged in the deal. American consumers felt the pinch when prices spiked; they'll feel it again if this arrangement collapses. Every dollar spent deploying ships, troops, and diplomats to the Persian Gulf and Mediterranean is a dollar not spent at home. The question isn't whether Iran deserves relief — it's whether Americans are getting anything concrete from a deal that one side won't implement and the other side won't honor.

The deal exists on paper. The fighting continues on the ground. Iran wants implementation before negotiation. Israel wants to keep bombing. The administration wants credit for diplomacy that hasn't produced results. American taxpayers are paying for all of it — and the only guarantee so far is that the next round of talks will be scheduled, postponed, and explained by the same people who can't make any of it stick.
