US Vice President JD Vance says President Trump is prepared to resume military action against Iran if nuclear negotiations fail. In remarks reported by multiple outlets, Vance characterizes the administration’s posture as ready to act—describing Trump as “locked and loaded”—while also stating that the US continues pursuing diplomacy. He says the goal of ongoing talks is to reach a deal that permanently prevents Iran from obtaining a nuclear weapon. Vance frames the negotiation effort as being conducted in good faith, suggesting the US is still working toward a diplomatic outcome rather than abandoning negotiations. If the talks do not produce the intended result, he indicates the administration could shift back to a military campaign. The statements emphasize a conditional approach: diplomacy is underway, but the US signals a preparedness to use force if Iran does not reach an agreement that blocks Tehran’s path to nuclear weapons.
