U.S. President Donald Trump and Iranian President Masoud Pezeshkian on Wednesday signed a memorandum of understanding aimed at ending the war between the two countries. The agreement calls for Tehran to dilute its stockpile of highly enriched uranium and waives U.S.-backed sanctions on the country, immediately allowing Iran to sell its oil freely in a major concession from Washington, according to details released by both countries.
The White House said Trump signed a memorandum of understanding on ending the war in Iran while at Versailles. Iran's chief negotiator Mohammad Bagher Ghalibaf also signed the agreement.
Switzerland confirmed on Thursday morning that initial talks between the U.S. and Iran are planned at the Buergenstock mountaintop resort in Switzerland on Friday.
"As things stand, the plan is still for the U.S. and Iran, along with mediators Pakistan and Qatar and other involved countries, to meet tomorrow at Buergenstock for initial negotiations about implementing the agreement.
"No further information is currently available regarding the schedule and details of this meeting," the Swiss foreign ministry said in a statement.
Trump, attending the G7 with other leaders in France, also withdrew at least one of his stated rationales for attacking Iran in the first place, saying it would be "unfair" for Tehran not to have ballistic missiles, having previously vowed to obliterate them.
"We're going to bomb the hell out of them if they violate the agreement," Trump said of Iran at a press conference. "I don't want them to. I want them to honor the agreement." He also called Iranians "smart people" as U.S. and Iranian negotiators work on a permanent truce over the coming 60 days, which Trump said he hoped would usher in peace in the Middle East and lower oil prices.
Earlier, he had said: "If I don't like it, if they don't behave, we'll go right back to dropping bombs right smack in the middle of their head, OK?"

Trump himself told reporters that he has signed the memorandum. "It's signed," Trump said "I signed it in Versailles. Just signed it."
Iran's leaders did not address the new threats while celebrating the moment, releasing photographs of what is believed to be the first agreement signed by both a U.S. and Iranian president since the Islamic Republic's founding in 1979.
"Everything we sought to achieve through military action, we obtained several times over through negotiation; it was not even comparable," Iran's lead negotiator Ghalibaf told state television about the agreement, which includes the unfreezing of billions of dollars in Iranian assets.
The 14-point agreement extends a cease-fire announced in April by another 60 days, including in Lebanon, to allow the two sides to negotiate a final truce. Both Trump and Iranian President Masoud Pezeshkian have digitally signed the memorandum in English and Farsi, U.S. and Iran officials said, with Iran's foreign ministry saying the agreement was already in effect as of Wednesday.
The memorandum includes an immediate end to the war on all fronts, including Lebanon, the full resumption of maritime traffic "with no charge" in the Strait of Hormuz, the lifting of a U.S. blockade of Iranian ports, the waiving of U.S. sanctions on Iran, the unfreezing of its assets, and a $300 billion investment fund for the Islamic Republic's post-war reconstruction.
Iran also undertakes not to build nuclear weapons, reaffirming a vow it had made for decades. It also agreed to the on-site "down-blending" of its stockpile of enriched uranium under the supervision of the International Atomic Energy Agency, although Trump had wanted to take it out of the country, which Iran has rejected.

Trump recanted his February promise to destroy all of Iran's missiles and "raze their missile industry to the ground."
"I'm saying that if other countries have them, it's a little bit unfair for them not to have some," Trump told reporters in Paris after leaving the summit.
G7 leaders hailed the agreement at their summit, held in the French town of Evian-les-Bains, an hour's drive along the shore of Lake Geneva from where the U.S. has said a formal signing ceremony for the U.S.-Iran agreement was due to be held across the Swiss border on Friday.
But Iranian foreign ministry spokesperson Esmaeil Baghaei cast doubt on this, telling IRIB's News Network that, because the two presidents had already signed, "No signing ceremony will be held in Switzerland."
Pakistani Prime Minister Shehbaz Sharif said both leaders had signed the agreement and endorsed him as a mediator.
He said in a post on X that the deal "shall enter into force with immediate effect and as a first step, Islamic Republic of Iran will instantly reopen the Strait of Hormuz and the United States of America will immediately lift the naval blockade."
Sharif had originally that there would still be a formal signing ceremony on Friday, even though both sides has already signed the memorandum. He removed that post shortly after it was uploaded, however, and reposted most of the same text a few minutes later – having removed a reference to Friday's ceremony, casting doubt on whether the ceremony will happen.
Iran's Foreign Ministry spokesman Esmaeil Baqaei also said that Friday's talks are not confirmed for now.
"The Friday meeting was confirmed until a few hours ago, but when it was decided that the presidents of the two sides (Iran and the U.S.) would sign the agreement, it was decided to pause consideration of the Friday meeting for now," Baqaei said.
Baqaei added that continued Israeli attacks on Lebanon would be considered a breach of the United States' commitment to the Islamic Republic.
French President Emmanuel Macron, meanwhile, published a video showing Trump signing the agreement. In his post, Macron said that "this agreement paves the way for lasting peace and allows the reopening of the Strait of Hormuz. It is an important step in the right direction for our compatriots that will soon enable a decrease in energy prices."
The official Iranian news agency IRNA also published a photo showing the Iranian president with a signed copy of the Iran-U.S. agreement.
