The Trump administration touted last year’s bombing of Iranian nuclear sites as one of its great military successes. But a strike to support protesters would need to be very different and could backfire.

After meeting with Israel's Netanyahu, Trump said he'd heard Iran is trying to rebuild its nuclear program, "and if they are, we're going to have to knock them down."

Hundreds of people have reportedly been killed in Iran as authorities crack down on protests against inflation and the government’s handling of the economic crisis, with thousands more arrested amid a nationwide communications blackout.

Trump ordered military assets positioned for a potential strike on Iran, the WSJ reports, as advisers warn a large attack could spark wider conflict.

Israeli officials have suggested the Trump administration delay large-scale strikes until the Iranian regime is even more strained, while one Arab official said there is “lack of enthusiasm from the neighborhood" for American military action in Iran right now.

As tensions rise between the US and Iran following the killing of protesters, the US Government has told citizens to ‘leave Iran now’, just hours after Donald Trump said ‘help is on the way’.
