President Donald Trump said the U.S. is prepared to resume military strikes against Iran if nuclear negotiations fail.

The warning signals a shift toward aggressive military deterrence to pressure Tehran into a nuclear deal. Officials said this posture is necessary to prevent Iran from successfully pursuing a nuclear weapons program [3].

Speaking from Dubai, United Arab Emirates, Trump said the U.S. military is positioned for immediate action. He said the country is just one hour away [1] from a massive strike campaign.

Vice President JD Vance supported the stance, saying that the U.S. is "locked and loaded" [2]. Vance said the necessity of these measures is linked to global security, arguing that an Iranian nuclear bomb would be the first domino in a global arms race [4].

U.S. officials said the rhetoric is intended to force a diplomatic resolution. The administration seeks to ensure that Iran does not acquire the capability to produce nuclear weapons, which would destabilize the region, and potentially the world.

These statements follow a period of fluctuating tensions between Washington and Tehran. By emphasizing the speed of a potential response, the administration intends to demonstrate that military intervention remains a primary option should diplomacy collapse [2].

"We are just one hour away from a massive strike campaign."

The administration is utilizing 'maximum pressure' tactics by combining the threat of immediate military action with diplomatic negotiations. By specifying a one-hour window for strikes, the U.S. is attempting to eliminate Iranian perceptions of hesitation, aiming to compel Tehran to accept stricter nuclear limitations to avoid a preemptive strike.
