After signing a memorandum of understanding with Iran on Sunday to wind down the war, Donald Trump claims the agreement is 'not final,' and the US may still bomb the Islamic Republic.

Speaking at the Group of Seven summit in France alongside Egyptian President Abdel Fattah El-Sisi, Trump told reporters that the MOU, which was signed by Trump and Vice President JD Vance, is not complete. 

'No, it's not final, it's a memorandum of understanding,' Trump said. 'If I don't like it, we will go back to shooting at them, dropping bombs on their head.' 

A senior administration official told the Daily Mail on Monday that Trump, Vance and Iranian Speaker of the Parliament Mohammad Bagher Ghalibaf signed a digital version of the MOU on Sunday. 

But Trump threw cold water on the agreement on Wednesday. 

'If I don't like it, if they don't behave, we will go right back to dropping bombs right smack in the middle of their head. Okay? Because they misbehaved for 47 years,' Trump said with a defiant tone. 

Leaked copies of the MOU have been circulating among government officials and media organizations, potentially complicating the matter, which Trump says is fluid. 

The President's proclamation comes less than 48 hours before VP Vance is expected to travel to Switzerland to sign the historic agreement. 

Trump has not confirmed whether he would attend, though the Secret Service typically recommends against both leaders traveling abroad simultaneously.
