美提出三大要求，遭伊朗拒绝，特朗普下令：对伊朗伙伴加25%关税

Core Viewpoint - The negotiations between the US and Iran in Muscat on February 6 marked the first face-to-face talks since June 2025, with the US presenting three main demands to Iran: halt uranium enrichment, limit ballistic missile development, and cease support for regional proxies [1][3]. Group 1: US Demands - The US demands are seen as a way to significantly weaken Iran's deterrent capabilities, particularly by stopping uranium enrichment, which Iran claims is for peaceful nuclear energy use [1]. - Limiting ballistic missile development aims to undermine Iran's ability to retaliate against external threats, particularly against US military bases in the Middle East [1][3]. - The demand to terminate support for regional proxies, such as the Houthis, is intended to reduce Iran's influence in the region and its ability to challenge US interests [3]. Group 2: Iran's Response - Iran has expressed a strong stance against the US demands, particularly regarding ballistic missile development, which it considers a sovereign right and non-negotiable [3]. - In a show of strength, Iran publicly displayed a missile facility just days before the negotiations, signaling its continued capability for retaliation [3]. Group 3: Economic Pressure - The US has implemented a strategy of maximum pressure, including a new executive order imposing a 25% import tariff on countries trading with Iran, although this approach may be impractical given the number of countries involved in trade with Iran, including major powers like China and Russia [5]. - The current negotiations do not represent a fundamental shift from the 2015 nuclear agreement, where both parties had opposing views on uranium enrichment and military capabilities [5]. Group 4: Potential Framework Agreement - A proposed framework agreement by mediators from Qatar, Turkey, and Egypt suggests that Iran could agree to halt uranium enrichment for three years and transfer its high-enriched uranium to a third country, while the US would sign a non-aggression pact with Iran [7]. - Despite the potential feasibility of this framework, the lack of trust due to past US policy changes raises concerns about its implementation [7].
