The Trump administration has said that Iran <a class="css-yywogo" href="https://www.nytimes.com/2026/02/06/us/politics/trump-iran-nuclear.html" title="">must agree to zero enrichment</a>, and on Wednesday Ms. Leavitt told reporters that ensuring “the end of uranium enrichment in Iran” remained a nonnegotiable demand for the president.</p><p class="css-ac37hb evys1bk0">Given such a wide gap, Mr. Malley said it was highly unlikely the Trump administration could quickly conclude a wide-ranging bargain with Iran, especially in such a short time. He called it more plausible that the two sides would find limited agreements that sidestep the most difficult matters, including the fate of Iran’s nuclear program and its stockpile of nearly 1,000 pounds of highly enriched uranium.</p></div><aside aria-label="companion column" class="css-ew4tgv"></aside></div><div data-testid="Dropzone-13"></div><div class="css-s99gbd StoryBodyCompanionColumn" data-testid="companionColumn-7"><div class="css-53u6y8"><p class="css-ac37hb evys1bk0">“It’s hard to imagine a comprehensive deal given the gaps and differing visions of both sides,” Mr. Malley said. “You can imagine a series of smaller deals that includes the Strait of Hormuz and some sanctions relief.”</p><p class="css-ac37hb evys1bk0">Ms. Maloney and others said the addition of Mr. Vance to the U.S. negotiating team was a notable shift in Mr. Trump’s diplomatic approach.</p><p class="css-ac37hb evys1bk0">It was Mr. Witkoff and Mr. Kushner who led <a class="css-yywogo" href="https://www.nytimes.com/2026/03/26/us/politics/trump-iran-talks.html" title="">two previous rounds of talks</a> with Iranian officials over the country’s nuclear program, one last spring and one in late February.

Nicholas Burns, who negotiated with Iran as a senior State Department official during the George W.

Iran has made recent public demands for <a class="css-yywogo" href="https://www.nytimes.com/2026/04/07/climate/strait-of-hormuz-law-of-the-sea-tolls.html" title="">lucrative payments</a> to allow commercial shipping through the waterway.</p><p class="css-ac37hb evys1bk0">Mr. Trump may have simplified matters somewhat during a national address last week when he suggested that <a class="css-yywogo" href="https://www.nytimes.com/2026/04/01/us/politics/trump-iran-war-nuclear-uranium.html" title="">he might no longer demand</a> that Iran surrender its uranium stockpile.

Israel could push to renew the war and pursue its goal of <a class="css-yywogo" href="https://www.nytimes.com/2026/03/22/us/politics/iran-israel-trump-netanyahu-mossad.html" title="">sparking a popular uprising</a> that would topple Iran’s surviving clerical leaders, which goes beyond Mr. Trump’s currently stated war aims.</p><p class="css-ac37hb evys1bk0">Mr. Trump will also face pressure from Iran hawks at home not to cut a deal of convenience with Iran that ends the war without resolving long-term issues.</p><p class="css-ac37hb evys1bk0">The influential talk radio host Mark Levin, who has Mr. Trump’s ear, has been highly critical of the cease-fire. The U.S. official said that Mr. Trump could sour on the agreement if those voices were not offset by prominent war critics like the former Fox News host Tucker Carlson.</p><p class="css-ac37hb evys1bk0">Mr. Trump could also be triggered by Iran’s boastful domestic messaging, which is consistent with the kind of posturing routine in Middle East diplomacy, but which might provoke a U.S. president highly attuned to appearances.</p><p class="css-ac37hb evys1bk0">Hours after the Tuesday cease-fire, Iran’s National Security Council released a statement celebrating the country’s “undeniable, historical, and crushing defeat” of the U.S. and claiming that Mr. Trump had agreed to a list of huge concessions, such as a full U.S. military withdrawal from the region, that Trump officials call fictitious.</p><p class="css-1n7yjps etfikam0">Julian E.
