Iran and the United States signed a memorandum of understanding on June 18, 2026, ending a regional conflict that began on February 28 with US-Israeli strikes. The agreement lays the groundwork for detailed negotiations on Iran’s nuclear program and sanctions relief for Tehran. Iran will not discuss its missile program in any future negotiations, according to corroborated reports. Iran’s foreign ministry spokesman Esmaeil Baqaei stated that Iranian missiles are only for firing, not for negotiations, and that Iran’s defense capability will not be discussed in any process or with any party. Ali Shamkhani, an adviser to Iran’s supreme leader, also said the Islamic Republic’s missile capabilities are non-negotiable. US Secretary of State Marco Rubio characterized Iran’s refusal to discuss ballistic missiles as a 'significant stumbling block'. According to the Times of Israel, the 14-point memorandum includes a declaration that Iran will never produce nuclear weapons. The Indian Express reported that Iran agrees to not build or buy nuclear weapons under a draft US peace deal. Iran’s President Masoud Pezeshkian affirmed in a speech to the UN General Assembly that his country has no intentions to build a nuclear bomb. US President Donald Trump hosted Israeli Prime Minister Benjamin Netanyahu at the White House amid the diplomacy between Washington and Tehran, according to Algemeiner.com.
