Rogers didn't think the North Korea summit went well for the USA and that Trump made a mistake in his negotiation tactics because he has such a hard stance.
"I don't consider the summit a failure".
As for Bolton, he flat-out refused to give an opinion on the matter that didn't align with the president.
The UN Security Council has so far restricted sanctions exemptions to non-commercial infrastructure projects and would likely need to pass an entirely new resolution on North Korea for inter-Korean economic activities to resume, which is hard to imagine until Kim takes deeper steps toward completely and verifiably relinquishing his nuclear weapons, said Lim Soo-ho, an analyst at the Seoul-based Institute for National Security.
But U.S. National Security Advisor John Bolton appeared on several Sunday morning talk shows to say last week's summit between Trump and Kim was not a failure, even though talks fell apart with no agreements.
"If North Korea commits to complete denuclearization- including its ballistic missile program and its chemical and biological weapons programs, the prospect of economic progress is there", Bolton said.
In return, Pyongyang was only offering to close a portion of the Yongbyon complex, a sprawling site covering multiple different facilities - and the North is believed to have other uranium enrichment plants.
Since Trump flew home to Washington, Kim has stepped assuredly into the spotlight, keen to show himself as a poised leader taking his rightful place on the global stage.
North Korea's requests focused on rolling back United Nations resolutions passed throughout 2016 and 2017, which target the DPRK's mineral and food exports, fuel imports and contain other relatively broad restrictions on the DPRK's inward and outward bound trade.
But that's not what the North Koreans put on the table this time around.
"What President Trump was trying to do was look at what was possible for them overall", Bolton told CBS. "I mean it's not unusual in these circumstances to find that there are additional concessions that the other side might make", Boltons said.
Speaking at the first National Security Council meeting he had presided over in eight months, Moon said the result of the US-North Korea summit was less than hoped for, but the February 27-28 summit in Hanoi served to highlight important advances in denuclearization talks.
He said the issue was whether North Korea would accept what the president called "the big deal" - denuclearizing completely - or something less, "which was unacceptable to us".
"They have been (producing nuclear fuel)".
However, Moon said that if all Yongbyon facilities were "terminated in entirety, it should be considered the North's denuclearisation has entered an irreversible stage".
McCarthy added that the United States left sanctions against North Korea that were named after Warmbier in place.
"I didn't think this [summit] went well for the president at all, more importantly for the US national security", he said.
And Bolton said Trump has "turned traditional diplomacy on its head, and after all in the case of North Korea, why not?"
USA national security advisor John Bolton denied Sunday that last week's nuclear summit with North Korea was a failure, despite President Donald Trump coming home empty-handed. "But I don't believe for one second that's why the talks collapsed". "That was my position long before I became President. I have no doubt of that whatever". Tapper asked the national security adviser.
