Trump administration signals change in narrative of US war with Iran

President Donald Trump said the fighting would continue until Iran’s “objectives” were completed. These objectives and the justification for the war remain in flux more than 48 hours after the conflict began.

The disagreements between Mr. Trump and his surrogates have led to confusion over how he and his advisers define the endgame for ending the escalating conflict.

President Trump began a military buildup near Iran after promising the rebels that “help is on the way” as protests against the Iranian government rocked the country in January. Since the attacks began on Saturday, the stated justifications have swung wildly around preventing Iran from acquiring nuclear weapons, toppling an Iranian regime that brutally suppresses dissent, preventing an imminent Iranian attack on U.S. interests, and following Israel’s lead.

This ambiguous message highlights broader questions about whether President Trump is pursuing purely military objectives or full-scale regime change.

The changing justifications and growing list of objectives have raised questions about the administration’s motives and the extent to which the United States will become embroiled in Iran, questions that have become more urgent as the death toll of U.S. service members has risen to six. This dynamic has infuriated Democratic members of Congress, who had primarily opposed the war, and some Republicans have also begun to question it.

“I think we’ve seen the objectives of this operation change four or five times,” Sen. Mark Warner (D-Va.), the top Democrat on the Senate Intelligence Committee, told reporters Monday after a meeting with Secretary of State Marco Rubio. “It was about Iran’s nuclear capabilities, then a few days later it was about removing ballistic missiles, then — in the president’s own words — it was about regime change… and now we hear it’s about the sinking of the Iranian fleet.”

“I don’t know if any of these goals, if met, would mean we’re at the end of the road,” Warner said.

Sen. Richard Blumenthal (D-Conn.) was more blunt in his assessment.

“The president is going all over the place,” he said.

As the invasion began on Saturday, President Trump said in a video message that his goal was to “protect the American people by eliminating the immediate threat from the Iranian regime, which is an evil group of very tough and fearful people.”

The president said the U.S. military would destroy the country’s missile silos, prevent it from acquiring nuclear weapons, destroy its terrorist proxy network and sink its navy. He also urged Iranians to overthrow the leadership that has ruled the country since 1979. This was a clear call for regime change and raised eyebrows even among some allies.

On Saturday, after President Trump’s “Truth Social” video confirmed the killing of Iranian leader Ayatollah Khamenei, an anonymous US official briefed the media on the operation. They said something different: the US launched a pre-emptive strike to thwart the threat of an imminent attack by Iran.

And on Sunday, President Trump spoke with countless media outlets, including CNBC. He told The Atlantic that Iran had waited too long in negotiations over its nuclear program and could have reached a deal, and told CNBC that the U.S. strike was “ahead of schedule,” although he did not give a date. He later told the Daily Mail that the war could last more than four weeks.

Late Sunday, President Trump said in a second video address that the fighting would continue “until all of our goals are achieved and we have a very strong goal.” He reiterated his call for a change of government, saying it was to ensure safety “for our children and their children.” He warned that U.S. military casualties could rise further.

On Monday, President Trump reiterated that his priorities are to destroy Iran’s missile capabilities, destroy its navy, prevent the country from acquiring nuclear weapons, and destroy its ability to finance terrorist proxies.

And then there are those close to President Trump, some of whom could be potential 2028 presidential candidates.

Secretary of Defense Pete Hegseth told reporters on Monday that the war was “not a so-called regime change war” but an effort to prevent Iran from building a “conventional shield” against its nuclear program.

Mr. Rubio offered a different characterization on Monday, arguing, as the administration did Saturday, that the mission was partly a pre-emptive strike. But Mr. Rubio seemed to suggest that an attack from Iran would only come after an attack on Iran by Israel, an ally of the United States.

“We knew the Israeli action was going to happen. We knew it would provoke an attack on U.S. forces. We knew there would be more casualties if we didn’t get ahead of the attack and pursue it,” Rubio told reporters before briefing key members of Congress. “We weren’t going to sit there and absorb the shock before responding.”

President Trump fired back Tuesday during a meeting with German Chancellor Friedrich Merz, saying, “No, I may have forced their hand,” referring to Israel.

Rubio also emphasized that the “objective” is to “destroy the missile capability.” Rubio echoed Trump earlier in saying that Iran is trying to build more missiles to protect its quest to build nuclear weapons.

“This had to happen no matter what,” Rubio said.

And Vice President J.D. Vance, who himself has honed his brand by avoiding another escalation of conflict in the Middle East, insisted on Monday that the war would not last long, saying of Trump: “We’re not going to rest until we accomplish that very important goal of keeping Iran from having a nuclear weapon.”

Analysts say the United States may be seeking both regime change and functional disarmament of Iran. This has been a long-term goal of the US administration for decades. They are looking at what targets both the US and Israel are attacking to determine motives. It is also possible that the United States and Israel are pursuing both goals separately.

“If you just look at what’s being attacked, you can certainly say they’re targeting both,” said Mark Cancian, a retired Marine Corps colonel and senior adviser at the Center for Strategic and International Studies. “But there’s also the question of who is aiming for what…so we may just be pursuing different goals.[Israel]is aiming for regime change and we are aiming for a nuclear program, a missile program, terrorism.”

Cancian said such a scenario could disrupt the final stages of the war.

“It may not make a big difference every day during the campaign, but it will make a big difference at the end of the campaign,” Cancian said. “I can imagine a situation where the Iranian government accepts[the US’s]terms, which is what happened in Venezuela. But I can also imagine a situation where Israel continues to bomb.”

“At some point, they’re going to have to make a decision. They don’t have to face that problem right now, but at some point they’re going to have to face it…It will be especially pressing if the Iranian government offers peace,” he said.
