Donald Trump thinks Iranians should overthrow their government if it refuses to negotiate on its nuclear program, but the US president is “still interested” in diplomacy, the White House said Monday.

“If the Iranian regime refuses to come to a peaceful diplomatic solution, which the president is still interested and engaging in, by the way, why shouldn’t the Iranian people take away the power of this incredibly violent regime that has been suppressing them for decades?” Press Secretary Karoline Leavitt said on Fox News.

US officials have warned Iran against hitting back at the US and Trump said after the strikes that any retaliation by Iran against the US would be met with a force far greater than that used in the weekend US attacks.

Trump’s administration has repeatedly said that its aim is solely to destroy Iran’s nuclear program, not to open a wider war. But in a social media post on Sunday, Trump spoke of toppling the hardline clerical rulers who have been Washington’s principal foes in the Middle East since Iran’s 1979 revolution.

“It’s not politically correct to use the term, ‘Regime Change,’ but if the current Iranian Regime is unable to MAKE IRAN GREAT AGAIN, why wouldn’t there be a Regime change??? MIGA!!!” he wrote.
