A last-minute Israeli airstrike on Beirut in the final hours leading up to the historic U.S.-Iran preliminary agreement sent shockwaves through diplomatic channels, sparking intense fears that the deal would collapse before it could be signed. However, a deliberate decision by Tehran to withhold an immediate military response kept the fragile negotiations on track.
The Israeli strike targeted locations in the Lebanese capital just hours before Washington and Tehran were scheduled to announce their breakthrough memorandum of understanding. The timing of the attack directly challenged previous warnings from Iranian officials, who had explicitly stated that further escalation would jeopardize the diplomatic process, with some hardliners openly threatening immediate retaliation.
According to a report by Axios citing sources familiar with the matter, the sudden bombardment triggered deep anxiety in Washington and among regional mediators, who feared that a fresh cycle of escalation would permanently derail months of backchannel diplomacy. Despite the immense pressure, Iran refrained from launching any immediate direct military action, allowing the drafting committees to proceed uninterrupted.
