A senior Iranian official told Reuters that Tehran would shift to a fully offensive military posture and could launch a “timely and precise” attack to break the US naval blockade if diplomacy failed, as the 60-day June memorandum expired and President Trump said Washington would not extend it.

Reuters reported on 17 August 2026 that the June 17 memorandum’s 60-day window for a broader nuclear and sanctions deal elapsed on Monday. Trump, asked whether the United States was seeking an extension, said no. The same package of reporting carried Trump’s Fox News threat that “if Oman gets in the way, we’ll bomb” the Gulf state over Hormuz-management talks; Oman is not a seeded theatre actor and that threat is recorded only as context, not as a strike. No fresh US or Iranian strike wave was reported the same day.

Verification: Confirmed

Evidence: Iran threatens new offensive while US rules out extending ceasefire deal, Iran says it will escalate if US does not honour deal within weeks

Confirmed Reuters reporting of the official’s on-record threat and Trump’s refusal to extend the MoU; the threatened attack is a stated intention, not a kinetic event.
