US ambassador Nikki Haley said Sunday the Trump administration's approach to the Iran deal is aimed at avoiding another situation like in North Korea.

"What we're saying now with Iran is don't let it become the next North Korea," the US ambassador to the United Nations said in an interview on NBC's "Meet the Press." President Donald Trump's declaration that Iran was violating the multilateral nuclear agreement and his threat that the US could exit it sent a message that North Korea should not expect the US to make a bad deal, Haley said.
