President Donald Trump (R-FL) warned Iran it will face severe attacks if it pursues a nuclear weapon or refuses a nuclear deal.

The warnings signal an escalation in U.S. pressure on Tehran to halt its nuclear ambitions, citing regional security concerns as the primary driver for the threats.

Speaking in Clive, Iowa, Trump said the next attack would be far worse if Iran does not agree to a nuclear deal [2]. This statement followed a previous warning issued on Jan. 27, 2026 [2]. The president also referenced a June 16 warning in which he said "all h*** will rain down" on the Islamic Republic if it attempts to obtain a nuclear weapon [1].

Trump said planned talks are Iran's "last chance" to avoid new strikes [3]. These negotiations are intended to deter Iran from obtaining nuclear capabilities and to pressure the government into accepting a formal agreement.

Despite the threats, Trump said he decided against carrying out major strikes against Iran at the urging of Gulf allies [3]. This indicates a tension between the administration's public warnings and the strategic requests of regional partners.

The administration's approach combines the threat of military force with a window for diplomatic resolution. Trump has maintained that Iran will never get nuclear weapons, positioning the current diplomatic window as the final alternative to military action.

"Next attack will be far worse" if Iran does not make a nuclear deal.

The administration is utilizing a 'maximum pressure' strategy, pairing explicit threats of military escalation with a final diplomatic offer. By citing the influence of Gulf allies, the U.S. acknowledges that while it possesses the capability for strikes, regional stability and coalition cohesion remain critical constraints on its military options in the Middle East.
