Core Viewpoint - The U.S. President Donald Trump stated that Iran will not be allowed to conduct any uranium enrichment activities, while Iranian officials indicated readiness to reject a new proposal from the U.S. regarding the nuclear deal due to unmet concerns [1][2][4]. Group 1: U.S. Position - Trump emphasized on social media that under a potential agreement, Iran would not be permitted to engage in any uranium enrichment activities [2]. - The U.S. proposal, presented by Middle East envoy Steven Wittekopf, suggested allowing Iran to continue low-level uranium enrichment for civilian purposes, contingent on closing underground facilities [4]. - Trump's statements appear to downplay Wittekopf's proposal, which includes significant compromises that may not satisfy Israel and pro-Israel U.S. lawmakers [4]. Group 2: Iranian Response - Iranian officials accused the U.S. of not changing its stance on uranium enrichment and failing to clarify sanctions relief, leading to a planned rejection of the proposal [7]. - Iran's Foreign Minister Abbas Araghchi indicated that a formal response to the U.S. proposal would be forthcoming [7]. - Iranian officials noted that the latest proposal contradicts the latest consensus reached in the fifth round of indirect talks, with the U.S. changing its position being a major obstacle to successful negotiations [7]. Group 3: Historical Context - The 2015 nuclear deal required Iran to limit its nuclear program in exchange for sanctions relief, but the U.S. withdrew from the agreement in 2018 and reinstated sanctions [5]. - Since May 2019, Iran has gradually ceased compliance with parts of the agreement, although it claims that its actions are reversible [5]. - Following Trump's re-election in January, efforts to reach a new agreement have seen five rounds of indirect talks, but core issues remain unresolved [5].
