Donald Trump’s likely casus belli for an attack on Iran – which would be the largest US intervention since the Iraq war – is fraught with contradictions, and his top advisers have been left to cover for him as the White House makes the case for intervention.

In his State of the Union address this week, Trump alleged that Iran posed a direct threat to the US and that the country was “working to build missiles that will soon reach the United States of America”. But that claim has not been backed up with evidence by the White House or the Pentagon, and US intelligence reports from just last year say that it would take Iran 10 years to develop an intercontinental ballistic missile that could reach the US.

Marco Rubio delivered a rare briefing to top US lawmakers on Iran, just a few hours before Donald Trump used his State of the Union address to say that Tehran would never be allowed to develop nuclear weapons.

Amid the largest deployment of aircraft and warships to the Middle East since the 2003 buildup to the Iraq war, Trump said he wanted to solve the confrontation with Iran through diplomatic means while claiming that Tehran was seeking to develop ballistic missiles that could reach the US, without providing further details.
