Trump says Iran deal 'isn't worth the paper it's written on'

US President Donald Trump told Fox News in an interview on Tuesday that he had given Iran a lot of chances, and dismissed the value of any deal with Tehran.

"I think an agreement with them isn't worth the paper it's written on. We gave them a lot of chances," Fox News quoted him as saying.

Trump also told Fox News that if Iran responds to the lastest US strikes, it will face a much stronger military response, warning the country could be "totally wiped out" if the conflict escalates further.
