Multiple authoritative and relevant primary sources indicate that Donald Trump maintained a stance of keeping military options open in dealing with Iran, and explicitly discussed support for Israel in the context of Iran's nuclear threat. Official reporting from credible outlets such as the BBC and Axios describe Trump telling Netanyahu that talks should continue while not ruling out military action. Axios further reports Trump's consideration of additional military deployments if negotiations failed, contextualized alongside Israel's concerns and requests, suggesting alignment with potential Israeli action. Policy-focused summaries confirm his cooperation with Israel on Iran's nuclear program, and credible accounts from Ynet News and think-tank analyses describe U.S. bolstering military assets to deter Iran and support Israeli security objectives. The post-event evidence of coordinated U.S.-Israeli strikes in June 2025 reinforces that his administration was willing to engage militarily alongside Israel when diplomatic efforts stalled. No major contradictory evidence appears in authoritative sources; while some emphasize his preference for negotiations, they do not negate the clear willingness to support Israeli military operations should talks fail. The combination of contemporaneous reporting, official policy statements, and subsequent events gives high confidence that Trump's stance amounted to a pledge to support Israeli military strikes if nuclear talks collapsed.
