The United States will need additional evidence that the North Korean leader Kim Jong Un is willing to give up nuclear weapons before President Donald Trump would meet him for a third summit, stated National Security Advisor John Bolton, Bloomberg reported.

“The president is fully prepared to have a third summit if he can get a real deal,” Bolton said. Asked if there had been any progress toward denuclearization, he responded, “I wouldn’t say we could say that at this point.”

Bolton’s comments were more pessimistic than that voiced by other members of the administration -- including Secretary of State Michael Pompeo -- about North Korea’s intentions and the prospects for a deal.

Before joining the Trump administration, Bolton was skeptical about the possibility of a deal, and the North Korean state media repeatedly criticized him, saying at one point that the country can’t hide its “repugnance” toward him.
