A confrontation between North Korea and the USA has been brewing for decades.
The world is crossing its fingers.
Haas offers a useful warning, though, as people around the world settle in to watch the show in Singapore: "Virtually no North Korea analyst inside or outside of the US government" expects Kim to actually give up his nukes.
Success on June 12 could also mean that the two leaders define further topics to discuss, such as rolling back North Korea's ballistic missile program and implementing a complete freeze on the production of nuclear materials.
And en route from Canada to Singapore, Trump unleashed a harsh Twitter attack on Trudeau, which was amplified Sunday on television talk shows by Navarro and White House economic adviser Larry Kudlow.More news: Poundworld prepares to appoint administrators in bid to avert collapse
"Trump is a publicity seeker".
Ahead of the meeting, Trump has dangled the carrot of a normalisation of diplomatic ties between the former foes and even a White House visit for Kim, which would confirm his arrival on the world stage.
United States and North Korean officials are meeting Monday at the Ritz Carlton in this island city-state to negotiate before a sit-down meant to settle a standoff over Pyongyang's nuclear arsenal. "But they just stopped right before they crossed that line".
Kim, who arrived in the city earlier on Sunday to participate in the much-anticipated meeting with US President Donald Trump, was accompanied by an army of his running bodyguards.
Other young South Koreans said they were too preoccupied with their search for work to pay attention to diplomacy. She led a North Korean delegation to the Winter Olympics in South Korea.
But some question why Kim should trust any guarantees given Trump's history of pulling out of accords - most recently the painstakingly negotiated Iran nuclear deal.
There was speculation throughout the day over whether Kim Jong Un had taken his private jet- an Ilyushin IL-62M - from Pyongyang, but official photos released by the Singaporean Ministry of Communications and Information showing Kim meeting Balakrishnan on the tarmac appear to reveal that he flew to Singapore aboard an Air China Boeing 747.More news: Bitcoin tumbles as hackers hit South Korean exchange Coinrail
Democrats say they are hope Trump can pull a strong deal off, though they express worry he could accept a bad deal just to secure an agreement. It comes as officials are revealing more details about meeting - the first between a U.S. president and North Korean leader. And the maximum, I think you know the answer to that. "We want him to succeed".
What has North Korea said?
So the summit was almost derailed by talk from Trump's hawkish National Security Advisor John Bolton of a "Libya model" of disarmament.
President Donald Trump listens during a meeting with Singapore Prime Minister Lee Hsien Loong ahead of a summit with North Korean leader Kim Jong Un, June 11, 2018, in Singapore.
The summit has been portrayed as a "get to know you" meeting.
A more middle-of-the-road result could be for statements about denuclearization followed by more high-level negotiations. Trump and Kim come from very different backgrounds and ideologies, and at 71, Trump is about twice as old as the North Korean leader.
But Trump said: "We could absolutely sign an agreement and we're looking at it", adding: "Sounds a little bit odd, but that's probably the easy part".More news: Australia head to Russia 'buzzing' after Hungary win
U.S. Secretary of State Mike Pompeo said last week that progress is being made in bringing the two sides together in their understanding of denuclearization.
