为何以色列需要美国帮助摧毁福尔多核设施？

Core Viewpoint - Israel's military actions against Iran will not cease unless the Fordow nuclear facility is destroyed, indicating a significant escalation in regional tensions and a potential need for U.S. military involvement [1][2]. Summary by Sections Israel's Military Strategy - Israel's military plans regarding Iran are independently formulated and encompass all elements of offensive action, maintaining ongoing communication with the U.S. without seeking direct involvement [1]. Fordow Nuclear Facility - The Fordow facility is located 90 meters underground, making it impervious to conventional weapons, necessitating U.S. military intervention for any airstrike to be effective [2]. - The facility is Iran's second uranium enrichment site, housing thousands of centrifuges, and has been accused by Israel of storing near-weapons-grade enriched uranium [2][4]. Historical Context - The Fordow facility was constructed during Ahmadinejad's presidency, officially declared to the International Atomic Energy Agency (IAEA) in 2009, and began uranium enrichment activities in December 2011 [4][5]. - Following the U.S. withdrawal from the Iran nuclear deal in May 2018, Iran resumed enrichment activities, with uranium enrichment levels reaching 83.7% by March 2023, close to the 90% required for weapons-grade material [5]. Challenges in Military Action - The facility's depth poses significant challenges for any military strike, as it was designed to withstand external attacks, with Israel having previously developed multiple plans to target it [6][7]. - The U.S. possesses the GBU-57 bunker buster bomb, capable of penetrating deep underground targets, but its deployment would require U.S. pilots and presents numerous technical and operational challenges [9][10]. International Implications - Any military action against the Fordow facility raises concerns about potential nuclear leaks and broader international repercussions, as highlighted by former U.S. military officials [10].
