Of course, the stakes for Trump's gamble to meet with Kim remain incredibly high, and the administration spent much of the day downplaying the chances for a lasting breakthrough. But Pompeo on Monday used a term Kim and his government has frequently used in internal messages: "complete denuclearization" of the Korean Peninsula.
Pompeo said the United States is prepared to take actions to provide North Korea with "sufficient certainty" that denuclearization "is not something that ends badly for them".
He would not be drawn on what might be on offer.
Tuesday's summit in Singapore is unlikely to be a "momentous event", Kirk Wagar tells CNBC.
Kim is to meet Trump on Tuesday morning to discuss the future of his nuclear program.
Scott Snyder, a U.S. -Korea policy specialist at the Council on Foreign Relations, told CNBC earlier on Monday that the summit is " essentially the normalization of Kim Jong Un and North Korea on the worldwide stage".
"The nuclear testing has got them to the point where they now get this meeting", he said.
The North Korean leader appeared completely boxed in by several dozens of men in black when he made a decision to take a walk near the luxury St. Regis hotel, where he is staying.
More than 2,500 journalists have convened here, with each leader's every movement tracked carefully.

Trump hopes the landmark talks will kick-start a process that eventually see Kim give up his nuclear weapons in an irreversible manner that can be verified internationally.
For decades the U.S. has been a sworn enemy. And that was some of its milder language.
It's the "changed era" that is important. Kim Jong-un needs to tell his people why he's willing to negotiate. However, others reported that the Air China Boeing 747 took off before the leader's jet did by an hour or two as a security measure to avoid making his mode of transportation known.
Mr Trump's first year in office was marked by bitter exchanges between himself and Mr Kim - as North Korea conducted several ballistic missile tests in defiance of the global community. But lawmakers are anxious Trump might not get enough in return during his initial talks with Kim. Meanwhile, Mr Kim has called Mr Trump "mentally deranged" and a "dotard".
Experts believe the North is close to being able to target the entire US mainland with its nuclear-armed missiles, and while there's deep skepticism that Kim will quickly give up those hard-won nukes, there's also some hope that diplomacy can replace the animosity between the USA and the North.
In early 2018, a remarkable turnaround in the relationship occurred.
TRT World's Oliver Whitfield-Miocic reports from Seoul, South Korea.
Given Trump is resentful about coughing up millions of dollars to station large numbers of U.S. troops overseas for the benefit of other countries - a somewhat distorted view - it's possible that he may be willing to accept a reduced United States military presence in the region.
Yet while both sides agree that these are the core objectives, previous accords have broken down because of disagreements over what these things actually mean in practice and over the timeline for implementation.
Delegates were outlining specific goals for what US President Donald Trump and North Korea's leader Kim Jong-un should try to accomplish and multiple scenarios for how key issues can be resolved, an official briefed on the discussions said. Another Rodman trip to North Korea was sponsored by online betting company Paddy Power, but that firm severed ties with Rodman in 2013 after taking heat for associating with the North Korean regime.
"It's important to remember who we are dealing with".
Mr Trump has said the highly anticipated talks represent a "one-time shot" at peace.

The dialogue was pretty terrible though and it wasn't made any better by the British-accented voiceovers. Are you looking forward to Just Cause 4? Where can I watch the Square Enix E3 2018 press conference?
