President Donald Trump has said he would count it as a personal defeat if Iran's regime is still in power when he leaves the White House. In a phone interview on Thursday, November 12, 2026, he also said he would not hesitate to strike Iran again and warned its leaders "will not exist any longer" if they kill a senior US official.

The remarks, made to the Salem News Channel, are his bluntest yet about Tehran, and came the same day he declared on social media that the United States does not need a deal with Iran at all.

Key Points

• Trump said it would be "a defeat" if Iran's regime is still ruling when his presidency ends: "Yes, that would be a defeat… Absolutely."
• He said he would strike Iran again "without hesitation" if "things go the other way": "It's possible I would do it right now."
• Asked what would happen if Iran killed a US official, such as Treasury Secretary Scott Bessent, he said those responsible "will not exist any longer."
• Trump claimed Iran's leadership is weakening, declaring: "The regime is collapsing."
• The same day, he posted on Truth Social that the US does not need a deal with Iran and told Vance to stop leading the talks.

What Happened

Trump gave the phone interview to the Salem News Channel on Thursday, November 12, 2026, and was asked whether it would be a defeat if the "Iran crazies" were still ruling when he leaves office. His answer was immediate: "Yes, that would be a defeat… Absolutely."

It was the first time the president has tied his record so directly to the fate of Iran's government. Until now, his stated aims have centred on Iran's nuclear programme and shipping security in the Strait of Hormuz.

Asked whether he would hesitate to strike Iran again, Trump replied: "If I saw things going the other way, I would do that. It's possible I would do it right now." On what Washington would do if Iran killed a US official, he named Treasury Secretary Scott Bessent as an example and said those responsible "will not exist any longer"; Bessent had been moved to a military base over alleged Iranian threats.

Background: A War in Its Ninth Month

The US-Iran war began on February 28, 2026, and is now in its ninth month, with the US blockading Iranian ports and guarding shipping in the Strait of Hormuz, while Iran has repeatedly targeted vessels and American assets.

Diplomacy swung sharply in ten days. On Monday, November 2, Trump said a deal was "coming together very nicely", and Vice President JD Vance, who led the talks, said Washington had made "progress" with "no strict deadline", after opening a channel to Mohsen Rezaei, Iran's top security official.

That track halted abruptly on Thursday, when Trump posted on Truth Social: "We don't need a deal with Iran. Those days have long since passed!" He ordered Vance to focus on corruption and crime in Democrat-run cities and states. Hours later, Trump said Gulf allies had asked him to pause large-scale attacks.

Trump: Iran Regime Survival Would Be a "Defeat"

The "defeat" remark matters because it reframes the war in personal and political terms. Trump is no longer presenting the conflict only as a dispute over nuclear weapons or shipping lanes. By his own measure, the outcome will now be judged by whether the government in Tehran is still standing when he leaves office.

That framing also raises the stakes for any future deal. A settlement that left Iran's leadership in place would, on Trump's own words, look like a defeat, making a return to the table far harder even as Gulf allies press for restraint. It is a marked change from early November, when both men were publicly optimistic about a settlement, before Vance blamed the Iran war for the Republicans' midterm losses.

Reactions and Quotes

Trump's own words were the sharpest of the day. On the regime's survival: "Yes, that would be a defeat… Absolutely." On using force again: "If I saw things going the other way, I would do that. It's possible I would do it right now." On the killing of a US official: those responsible "will not exist any longer".

His Truth Social post was equally blunt: "We don't need a deal with Iran. Those days have long since passed! We've got their money, Hundreds of Billions of Dollars, and we've got their Strait!" Vance, who had led the talks for months, had struck a different note ten days earlier, saying Washington had made "progress" with "no strict deadline". Iran has not publicly responded to the post.

Why It Matters

The remarks set a new public benchmark for the war, and one Trump himself will be judged against. If Iran's leadership is still in place when his presidency ends, the president has now said, in advance, that he will have failed.

For the region, a president who has defined regime survival as defeat has less room to compromise, and allies pressing for a negotiated end face a White House locked into a harder line. At home, the war is already a political liability: Vance blamed it for the Republicans' midterm losses and the president's approval rating is at record lows.

What Happens Next

The immediate question is whether the talks Vance led are finished for good, or pressure tactics before a return to negotiations. For now, the channel to Rezaei appears closed, and no meeting date had been set even before Thursday's reversal.

Military options remain open: Trump has said he would strike "without hesitation" if things move the other way, while Gulf allies press for a pause. Watch for Tehran's response, any movement of US forces in the Gulf, and whether the administration acts on the warning if Iran is blamed for a further attack.
