US Defense Secretary Pete Hegseth has said that the United States is fully capable of launching a massive military strike against Iran, warning that such an operation could be among the most powerful seen since World War II.

According to international media reports, Hegseth made the remarks in a post on X, where he backed President Donald Trump's tough stance on Iran. He said the US military is fully prepared for any mission and remains on high alert to respond to any emergency.

The Pentagon, he added, has ensured that American forces are in a complete state of combat readiness and can carry out immediate military action if ordered. Hegseth stressed that the US military stands ready to respond quickly to any threat.

His statement comes at a time of growing tensions between Washington and Tehran, with both countries continuing to exchange strong warnings and accusations. The latest comments are expected to fuel concerns about the possibility of further escalation in the Middle East.

Earlier, President Donald Trump also claimed that the United States could launch military attacks against Iran of a scale rarely seen since World War II if the situation demanded such action.

Defense analysts believe the repeated warnings from senior US officials could increase regional instability and raise fears of a wider conflict. Meanwhile, the international community continues to call for restraint, diplomacy, and dialogue to prevent the crisis from turning into a major military confrontation.
