President Donald Trump is grappling with a pivotal decision in the escalating Israel-Iran conflict, now in its fourth day: whether to provide Israel with the GBU-57 Massive Ordnance Penetrator (MOP), a 30,000-pound bunker-busting bomb capable of destroying Iran’s deeply buried Fordo nuclear enrichment facility. The bomb, which only U.S. B-2 Spirit stealth bombers can carry, is seen by experts as the sole weapon able to penetrate Fordo’s fortified underground structure. Israel lacks both the MOP and the bombers needed to deploy it, making U.S. involvement critical to achieving Jerusalem’s goal of dismantling Iran’s nuclear program.
Iranian officials, including Foreign Minister Abbas Araghchi, have warned that U.S. participation in attacks on Iran’s nuclear sites would jeopardize any chance of a nuclear disarmament deal, which Trump has publicly supported. On Monday, Araghchi signaled openness to diplomacy, stating, “If President Trump is genuine about diplomacy and interested in stopping this war, next steps are consequential.” However, Trump’s social media post urging Tehran’s evacuation and his early departure from the G7 summit in Canada to address the crisis suggest a potential shift toward military action.
The Fordo facility, buried under mountains and capable of enriching uranium to near-weapons-grade levels, remains a linchpin of Iran’s nuclear ambitions. Experts like Brett McGurk, a former Middle East advisor to four U.S. presidents, emphasize that if Fordo continues enriching post-conflict, Israel’s strategic objectives will fall short. U.S. military exercises over the past two years indicate that destroying Fordo would require multiple B-2 strikes, with successive GBU-57 bombs targeting the same entry point, a mission only American pilots and aircraft can execute.
