US Defense Secretary Pete Hegseth has sent a strong message to Iran, saying the American military is fully prepared to act if Tehran continues to pursue nuclear capabilities. He made it clear that his department will carry out whatever President Donald Trump demands if Iran crosses that line.

Hegseth stressed that President Trump’s position on Iran has not changed. According to him, the US has already given Iran the chance to choose diplomacy, but military options remain firmly on the table.

“When President Donald Trump said, ‘Iran won’t have a nuclear bomb,’ he meant it… With Iran right now, you ensured they have all options to make a deal, they should not pursue nuclear capabilities, or we will be ready to deliver whatever this President expects of the War Department,” Hegseth said.

Trump repeats military warning to Tehran

President Trump has repeatedly warned Iran of serious consequences if it refuses to negotiate with the United States. He has claimed that a powerful US naval force is either heading towards Iran or already positioned near the country.

Trump has described the deployment as a “beautiful armada,” saying it signals America’s readiness to act if talks fail. The president has linked this military pressure directly to Iran’s nuclear programme.

‘Come to the table,’ Trump urges Iran

In a fresh message on Truth Social, Trump said a “massive armada is heading towards Iran with great power, enthusiasm, and purpose.” He added that the fleet, led by the Aircraft Carrier Abraham, is larger than the one earlier deployed near Venezuela.

Trump again urged Iran to enter negotiations without delay and agree to a deal that rules out nuclear weapons.

“Hopefully Iran will quickly ‘Come to the Table’ and negotiate a fair and equitable deal - NO NUCLEAR WEAPONS - one that is good for all parties. Time is running out, it is truly of the essence!” Potus said.

Rubio warns of uncertainty if Iran’s regime collapses

US Secretary of State Marco Rubio has also shared concerns about the wider impact of any major political change in Iran. He told lawmakers that if Iran’s current ruling system were to fall, the country could face a serious leadership crisis.

Rubio said power in Iran is divided among the Supreme Leader, the Islamic Revolutionary Guard Corps (IRGC), and several so-called elected officials. However, he noted that these individuals often lack real authority without approval from senior clerics.

According to Rubio, this fragmented structure makes it impossible to predict who would take charge if the regime collapsed.

“That’s an open question," Rubio told the committee. “No one knows what would take over."

Tensions remain high amid nuclear standoff

The latest statements highlight rising tensions between the US and Iran. While Washington continues to push Tehran towards negotiations, it has also made clear that it is prepared for military action if Iran refuses to abandon nuclear ambitions. The situation remains uncertain, with diplomacy and force both in play.
