When President Bill Clinton struck a landmark deal with North Korea in 1994, the isolated nation agreed to take a variety of specific steps that included freezing and later dismantling its nuclear program, as well as opening its facilities to worldwide inspectors. The president wants the complete, verifiable and irreversible dismantling of his nuclear weapons program. During a press conference, Trump credited Warmbier, who was arrested in 2016, for the historic summit taking place and added that he did not "die in vain".
Trump and Kim signed a joint statement Tuesday that - while short on details - committed to the denuclearization of the Korean Peninsula and said the two nations would hold "follow-on negotiations".
"The President's comments [were] very positive and the Statement touches on a new relationship with North Korea, and end to the Korean War, complete denuclearization of the Korean Peninsula and recovering POW/MIA remains - all positive commitments", he said. This has always been a point of contention for the North Koreans, especially as the exercises have expanded to include offensive drills, but it raises the question of how this concession fits into a larger process.
Trump announced that he will be freezing USA military "war games" with its ally South Korea while negotiations between the two countries continue.
A few other conservatives expressed dismay at seeing the United States and North Korean flags side-by-side, and viewed Mr Trump's solicitous manner and warm words for Mr Kim as too much, given his nation's history of human rights violations.
"My whole life has been deals".
"If I have to say I'm sitting on a stage with Chairman Kim and that gets us to save 30 million lives - it could be more than that - I'm willing to sit on a stage, I'm willing to travel to Singapore, very proudly", Trump said.
"I looked at the document and I said, 'Is this for real?'" he said.
Trump's scorecard is far more mixed.
In the interview, Rodman bawls while telling CNN host Chris Cuomo about the death threats he received when he first came back from meeting with Kim Jong-un in 2013. But under the deal, the regime froze its nuclear activities and agreed to dismantle nuclear facilities in return for oil and two light-water nuclear reactors for electricity.
Trump planned to speak to reporters after concluding the summit, the White House said.
And of course, Trump being Trump, there's no guarantee he'll adhere to the agreements set out in the joint statement, and no assurance he won't ruin everything with a tweet after seeing coverage he doesn't like on TV. There was not even a pledge that either side "shall" take action; just the assertion that North Korea will "commit to working towards" denuclearisation, which it sees as a general, not unilateral, process. Trump has dangled the prospect of economic investment in the North as a sweetener for giving up its nuclear weapons. It was brutal. But a lot of people started to focus on what was going on, including North Korea.
Alluding to the North's concerns that giving up its nuclear weapons could surrender its primary deterrent to forced regime change, Secretary of State Mike Pompeo told reporters that the USA was prepared to take action to provide North Korea with "sufficient certainty" that denuclearization "is not something that ends badly for them".

In four bullet points, they laid out goals of future rounds of negotiations without specifying what immediate steps either side would take.
In addressing an issue closer to home, Mr Trump said that United States college student Otto Warmbier did not die in vain days after he was released from North Korean custody in 2017, as his death helped initiate a process that led to the historic summit in Singapore.
As the screens above Trump emphasised, he certainly had.
"It marks the beginning rather than the culmination of a process", said Snyder.
