Trump team offers shifting views of US goals as Iran war engulfs Mideast

US President Donald Trump on Monday addressed mounting criticism that he hadn't yet explained why now was the right moment to start a war with Iran or share a vision for what the endgame might be in a conflict that shows no signs of de-escalating.  

The frustration is becoming palpable, not just from critics on the left but also from his MAGA base as the conflict spreads and the death toll rises across the Middle East. Reports of the first US casualties only underscored the political risk.   

Trump came to power promising to keep the US out of foreign wars. Instead, in the first 14 months of his presidency Trump launched offensives on seven nations, ordering more strikes just in 2025 than his predecessor Joe Biden did in four years.

Between the launch of US-Israeli air strikes on Iran early on Saturday and his first live remarks on Monday, Trump gave an array of telephone interviews that offered little in the way of clarification. 

The New York Times reported that in a brief, six-minute chat with Trump on Sunday, the US president “offered several seemingly contradictory visions of how power might be transferred to a new government – or even whether the existing Iranian power structure would run that government or be overthrown”.

Trump also left open the possibility of a US ground war, telling the New York Post that, unlike previous presidents, the idea didn't unnerve him.

“I don’t have the yips with respect to boots on the ground. Like every president says, ‘There will be no boots on the ground.’ I don’t say it.”  

But Trump admitted that the breadth and vigour of Iran's retaliatory attacks on Gulf Arab states was unexpected, telling CNN that it "was probably the biggest surprise". 

Four US goals 

As calls for answers grew from both allies and adversaries, Trump and his top aides sought to clarify US objectives on Monday.

In his first public remarks on the Iranian offensive from the White House, Trump laid out four military objectives for the war: to destroy Iran's ballistic missile capabilities, end Tehran's financial and military support for allied militant groups, prevent it from developing a nuclear weapon and "annihilating" the Iranian navy.  

"The regime's conventional ballistic missile programme was growing rapidly and dramatically, and this posed a very clear colossal threat to America and our forces stationed overseas," Trump said ahead of a Medal of Honor ceremony. 

A former intelligence official told the Washington Post that US agencies were concerned by how quickly Iran was able to rebuild its missile programme it was bombed by US and Israeli forces last June. “If you wait a year from now, maybe the regime will have stabilised, the missile programme will be more populated and federated,” the former official said.

'No stupid rules' 

The United States has traditionally cloaked its military engagements in idealised notions – seeking to install democracies in Afghanistan and Iraq, for example, alongside more mercenary objectives.   

Defense Secretary Pete Hegseth, however, made clear on Monday that was no longer the case.

"No stupid rules of engagement, no nation-building quagmire, no democracy-building exercise, no politically correct wars," he said – in one breath rejecting both longstanding American idealism and the very rules that military leaders have long credited with making US forces among the most respected and well-disciplined in the world. 

Hegseth did not cite any nuclear threat from Iran, reiterating that US-Israeli strikes on Iran last June “obliterated their nuclear programme to rubble”.

Instead, he said aerial threats justified the Iran mission. “Iran was building powerful missiles and drones to create a conventional shield for their nuclear blackmail ambitions,” he said. 

“This is not a so-called regime-change war, but the regime sure did change, and the world is better off for it,” Hegseth said. 

He also sought to allay concerns that the Iran offensive could signify the start of an open-ended US military entanglement in the Middle East.

"This is not Iraq," he said. "This is not endless."  

'Imminent threat'? 

US Secretary of State Marco Rubio offered a different view of America's casus belli, saying the US decided to strike "preemptively" after learning that Israel was about to attack Iran. 

An Israeli strike would have prompted Iran to retaliate against US forces, Rubio said, so the United States needed to act.

"We knew that there was going to be an Israeli action," Rubio told reporters. "We knew that that would precipitate an attack against American forces. And we knew that if we didn't preemptively go after them before they launched those attacks we would suffer higher casualties," saying the situation posed an "imminent threat". 

He added that the United States would "love" it if the Iranian people "overthrow this government" but said it was not a US objective.

Rubio denied, however, that the United States was "forced" into action because of Israeli plans, insisting "this operation needed to happen". 

Despite the administration's renewed efforts to provide answers, some noted that Trump's goals might remain undefined by design. 

"I think he's basically keeping it ambiguous, so that whatever happens he can claim it was a huge victory," said military historian Max Boot, a senior fellow at the Council on Foreign Relations, in comments to AFP.

"He will claim vindication no matter what happens."
