Donald Trump has plunged the United States into its most significant conflict in decades over a “feeling”. It’s not his political opponents saying this, but the White House itself.

Throughout the first week of the war with Iran, the US president has prioritised impulse and emotion over explanations and reasoning.

“I hope you’re impressed,” Trump, a former reality TV host, told an ABC News reporter on Thursday. “How do you like the performance?”

Official government accounts are posting clips on social media that present the military operation like a video game, often with sharp captions that would suit a blockbuster war film.

“This could be the first war ever launched based on vibes,” joked American comedian and talk show host Jimmy Fallon this week.

Journalists on Wednesday bombarded White House press secretary Karoline Leavitt with questions about what motivated US military intervention — which Trump oversaw from his luxury Mar-a-Lago residence in Florida.

She replied that the president had acted because he “had a good feeling that the Iranian regime was going to strike United States assets and our personnel in the region”.

‘Incoherent, immoral, arrogant’

Experts said the Trump administration has taken a new approach in how it has sought to justify and communicate the military action to the public.

Sean Aday, a public relations professor at George Washington University, said he has “never seen worse messaging in wartime from a US administration”.

“It’s been a combination of incoherent, immoral, arrogant, amateurish, and at times trafficked in outright fabrication,” he told AFP.

Aday contrasted it with ex-president George W. Bush’s attempts to justify the 2003 US invasion of Iraq, whose administration spent “nearly a year and a half trying to persuade the public it was necessary”.

Richard Haass, a former US diplomat, pointed to how Trump has largely ignored formal national security processes, “having spent the better part of the last year hollowing out the national security apparatus”.

The National Security Council, a body that helps the president shape his diplomatic and military strategy, has been significantly downsized since Trump returned to power in January 2025.

Marco Rubio now combines the roles of secretary of state and national security adviser — positions that were previously separate.

Contradictory comments

Trump has been vague about both the reason for entering a war with Iran and the objectives being pursued.

Instead of holding press conferences he has given several short phone interviews with reporters, producing a mosaic of contradictory comments.

And while his cabinet members state Washington is not seeking regime change, the US president has insisted that he should be involved in choosing Iran’s next supreme leader after the assassination of Ayatollah Ali Khamenei.

Trump has also brushed aside economic concerns from the conflict which has driven up the price of gasoline — a potential vulnerability for his Republican party ahead of midterm elections this year.

A poll released on Wednesday by NBC shows that 52 per cent of US voters oppose the military action in Iran.

By contrast, the start of the war in Afghanistan in 2001 was met with strong approval, and the public initially supported the offensive launched in Iraq.

But on both Afghanistan and Iraq, negative opinions grew as the conflicts dragged on.
