尽管特朗普发出警告，但伊朗远未具备制造洲际弹道导弹能力

Core Viewpoint - Iran faces significant technological challenges in developing intercontinental ballistic missiles (ICBMs) capable of striking the U.S. mainland, which raises questions about the justification for urgent military action by the Trump administration against Iran. Unless there is a major diplomatic breakthrough, the likelihood of military action is increasing [3][22]. Group 1: Iran's Missile Development - Experts indicate that Iran's ambitions to develop missiles that can reach the U.S. are hindered by high technical barriers, allowing time for negotiations to limit Iran's missile development [4][22]. - Iran does not acknowledge the development of ICBMs and shows no signs of willingness to abandon or limit its short- and medium-range missile arsenal [5][23]. - Iranian Foreign Minister Zarif stated that Tehran has intentionally limited the range of its ballistic missiles to 2,000 kilometers for deterrence purposes, while U.S. Secretary of State Rubio countered that Iran is clearly seeking ICBMs [6][24]. Group 2: Technical Challenges - To create ICBMs capable of reaching the U.S., Iran must overcome multiple core technological hurdles, including developing heat shield technology for re-entry vehicles and precision guidance systems [7][25]. - The U.S. Defense Intelligence Agency predicted that if Iran modifies its satellite launch systems for ICBM use, it could deploy up to 60 intercontinental missiles by 2035 [8][26]. - Experts believe that Iran's space launch program serves as a cover for ICBM development due to the shared technology involved [8][26]. Group 3: Nuclear Capability and Missile Matching - Iran needs to develop miniaturized nuclear warheads that can fit into re-entry vehicles to enable its missiles to carry nuclear payloads, which is a more time-consuming process than quickly building a rudimentary nuclear device [9][27][28]. - Currently, Iran is not enriching uranium to weapons-grade levels, as confirmed by Rubio [11][29]. Group 4: Regional Military Impact - Iran relies on short- and medium-range ballistic missiles to compensate for its air force's weaknesses, with its missiles capable of covering U.S. military bases in the Middle East and Southern Europe [13][31]. - The U.S. has deployed land-based missile defense systems in Romania and Poland to counter potential threats from Iranian missiles to Europe [13][31]. - Despite a stagnation in its nuclear program, Iran's conventional missile and drone capabilities pose a significant threat to Israel and Gulf states [15][33]. Group 5: Negotiation Stalemate - There are substantial divisions in U.S.-Iran negotiations, with some Middle Eastern countries suggesting that talks should focus solely on nuclear issues, postponing discussions on limiting Iran's missile capabilities [16][34]. - The Trump administration has shown no indication of willingness to set aside missile issues in negotiations [17][35]. - U.S. officials are concerned that without resolving these issues while U.S. military forces are concentrated in the region, Iran is unlikely to compromise [18][36]. - Rubio emphasized that Iran's refusal to discuss ballistic missile issues is a significant problem [19][37].
