Trump signed a 14-point Memorandum of Understanding with Iranian President Masoud Pezeshkian on June 17, 2026, committing to end military operations and reopen the Strait of Hormuz. Iran agreed to downblend its stockpile of highly enriched uranium under IAEA supervision and reaffirmed it won't develop nuclear weapons. The US committed to "at least $300 billion" in reconstruction funding with regional partners and pledged to lift all sanctions on an agreed schedule. The deal defers specific nuclear terms — enrichment levels and future enrichment rights — to the 60-day final deal negotiations. Any final deal also requires a binding UN Security Council resolution. Oil prices peaked at $126/barrel intraday during the war and fell roughly 38% to about $80/barrel by the signing.

1. The War Was Costing $600 Million a Day (Trump, Vance)

Trump's case is simple: ships were losing $600 million a day, and now they're not.

Ships are moving again. Trump made the economic argument directly: "If we keep bombing, those ships won't be going, and we're talking about 500, 600, 700 million dollars a day. That's a lot of money." The Strait of Hormuz blockade had removed an estimated 14 million barrels daily from global supply since late February.

The $300 billion fund is private investment, not US government money. Companies from the US, Gulf states, Asia, South America, and Africa committed to participate via loans and project financing. Reuters reported more than half of the money is already pledged. VP JD Vance described it as "funded by the Gulf Coast coalition." Trump: "We're not putting up 10 cents."

Iran's nuclear stockpile is getting destroyed. Vance told CBS the IAEA and the US "are going to help Iran destroy the highly enriched stockpile" and that nuclear inspectors will "absolutely" return to Iran. Point 8 of the MOU requires Iran to downblend its 460 kilograms of 60%-enriched uranium under IAEA supervision.

2. But Iran Was Already Losing (Cassidy, Scott, Tillis, Cruz)

Before the war, the US had Iran under maximal sanctions. Now those come off. To Senate hawks, that's the whole problem.

Iran was losing before this war started. Sen. Bill Cassidy, R-LA, laid out the before-and-after: "Before the war, the strait was open, Iran was being crushed by sanctions, and 13 service members were still alive. Now, 13 Americans are dead, families have paid billions at the pump, sanctions will be lifted, and the bombing has stopped." He called it "the worst foreign policy blunder in decades."

The $300 billion fund is the flashpoint. Sen. Rick Scott, R-FL: "I can't imagine how I would support giving them $300 billion." "Republicans are not the party of Barack Obama that throws money like that out to them." Sen. Ted Cruz, R-TX: "History teaches that giving billions of dollars to theocratic lunatics who want to murder us is not a good idea." Trump Jr. responded by publicly calling Cruz a liar.

The nuclear terms still aren't settled. Sen. Thom Tillis, R-NC, called the deal "doomed to fail" for lack of congressional oversight: "I need more than 14 points." Semafor reported June 16 that senators from both parties have united around requiring a congressional vote under the Iran Nuclear Agreement Review Act of 2015. That law gives Congress a 30-day review window for any Iran nuclear agreement. Trump signaled on CNBC he was open to sending the details to Congress.

3. ...And Israel Isn't Stopping Either (Netanyahu, Ben-Gvir, Katz)

Israel signed nothing. The Lebanon clause is the line where this deal could collapse first.

Israel isn't bound by the deal. Prime Minister Benjamin Netanyahu told Trump directly that Israel "does not consider itself bound by the Lebanese clause" and "intends to continue its military operations against Hezbollah." His cabinet backed him unanimously. Defense Minister Israel Katz: "The IDF will remain in the security zones in Lebanon...without any time limit." National Security Minister Itamar Ben-Gvir: "Trump's agreement does not bind us."

The US and Iran already disagree about what they signed. The MOU's Lebanon language says military operations cease "on all fronts, including in Lebanon." Iran's Foreign Minister Abbas Araghchi said "any continued occupation of Lebanese territory will be regarded by us as a violation." A US official told reporters the deal "did not call for an Israeli withdrawal." Hezbollah is not a signatory to the MOU. Israeli intelligence privately assessed that Iran's supreme leader has no intention of reaching a final nuclear agreement and approved the MOU mainly to reopen the Strait and secure economic relief.

4. Democrats Just Want to See the Text (Schumer, Coons)

Democrats aren't against ending this war. They want to know what they're agreeing to.

The deal text still isn't public. Senate Minority Leader Chuck Schumer called for a classified Gang of Eight briefing, a full congressional briefing, and public disclosure of the MOU text. "It's been two days since Trump claimed he had reached an 'understanding' with Iran, and he still hasn't released any details."

The 2015 review law applies. Sen. Chris Coons, D-DE, co-author of the Iran Nuclear Agreement Review Act, said congressional review procedures would "absolutely" apply to whatever gets finalized in the 60-day window. That law requires the president to submit any Iran nuclear agreement to Congress within five days of signing — triggering a 30-day review period. Sen. Tim Kaine, D-VA: "We're giving a lot more to get a lot less than we got in the JCPOA."

Where This Lands

The 60-day clock started June 17. Trump and his advisers say the war is over and Iran's nuclear stockpile is coming down. GOP hawks say Iran walked away from the war stronger than it entered — sanctions gone, strait reopened, $300 billion on the table. Prime Minister Netanyahu says Israel isn't bound by the Lebanon clause. Iran's foreign minister says that means Israel is already violating the MOU. Democrats say they can't evaluate any of it until they see the text.
