Donald Trump ordered military strikes on Iran, specifically targeting key nuclear facilities, in June 2025. This decision followed a complex context of escalating conflict in the region. Initially, Trump offered Iran a two-week window for diplomacy, but after backchannel negotiations failed and after Israeli airstrikes on Iran's nuclear and military sites, Trump saw an opportunity to act. The timing was influenced by U.S. intelligence assessments suggesting Iran's military position was weak, along with Israeli actions that had degraded Iran's air defenses and proxy networks. Trump's main goal was to prevent Iran from developing nuclear weapons, which he opposed strongly, while trying to avoid full-scale war. The strikes were intended to significantly weaken Iran's nuclear program and were also driven by political and military calculations about the regional balance of power and U.S. interests. The sequence began amid an ongoing conflict between Iran and Israel, with Iran retaliating for Israeli strikes, and the U.S. coordinating with Israel. Trump publicly indicated willingness to seek a peaceful solution but proceeded with the strikes when diplomacy faltered. The operation involved precision attacks on facilities at Fordo, Natanz, and Isfahan, aiming to cripple Iran's uranium enrichment capabilities. The strikes represented a significant escalation and were partly a response to continuous provocations and perceived threats from Iran's nuclear ambitions and regional activities. In summary, Trump attacked Iran in 2025 to halt Iran's nuclear program, exploit a perceived strategic opportunity after Israeli actions and intelligence assessments, and to assert U.S. power in the Middle East, while having initially attempted diplomacy that ultimately failed.
