Iran’s U.N. mission said it would be willing to discuss its nuclear program if talks were restricted to military concerns, after its supreme leader appeared to reject President Trump’s offer to start discussions.

Then US President Barack Obama negotiated the Joint Comprehensive Plan of Action or the JCPOA in 2015 and signed it along with the five permanent members of the UN Security Council, Germany, the EU and Iran.

Trump’s remarks represent a shift for the president, who in 2018 withdrew the United States from a nuclear deal with Iran.

U.S. President Donald Trump says he sent a letter to Iran's Ayatollah Ali Khamenei, something that was not immediately confirmed by the supreme leader.

President Trump said he sent a letter to the Iranian government seeking to negotiate a deal to prevent Tehran from acquiring a nuclear weapon. The White House did not release the letter or further describe its contents.

President Donald Trump said he wants to negotiate a nuclear deal with Iran and sent a letter to its leadership this week suggesting talks with the Islamic Republic, which the West fears is rapidly nearing the capability to make atomic weapons.

Ayatollah Ali Khamenei, Iran's supreme leader, said in a series of X posts Saturday he would not negotiate a nuclear deal with the U.S. due to its demands.

Ayatollah Ali Khamenei decried “bullying governments” in an apparent response to a letter the White House sent to Iran earlier in the week.
