Following a second surprise visit to Pyongyang by now Secretary of State Mike Pompeo, planning is complete for the historic meeting between President Donald Trump and Kim Jong-un in Singapore on 12 June.
In other words, there's nothing new about North Korean talk of denuclearization - or the release of the three USA prisoners held in Pyongyang (spare a thought for US student/prisoner Otto Warmbier, who was returned in a coma and died). "We will both try to make it a very special movement for the World Peace".
That was also when South Korea began deploying anti-ship missiles and strengthening its fleet of patrol ships in its western seas, which made North Korean hijacking operations more hard, analysts say.
"We're prepared to open trade and investment as soon as we can", John Bolton, Trump's national security adviser, said on ABC's "This Week".
And going back to "maximum pressure" if the talks fail is not really an option.
Since then he has regularly flown domestically, displaying a passion for air travel that is in stark contrast to his father and predecessor Kim Jong Il, who hated flying and only used high-security trains for overseas trips during his 17-year term.
Further, Kim is only known to have travelled overseas for the first time this year, with visits to China and a brief sojourn across the high-security border into South Korea for a historic meeting with President Moon Jae-in in April.
The Southeast Asia city-state has long acted as a bridge between the United States and China, with successive prime ministers offering Oval Office occupants their cherished geopolitical counsel.
Tourists are mimicking the historic handshake between the two leaders.
In his memoir that hit shelves Monday, Thae added: "More people should realise that North Korea is desperately clinging to its nuclear programme more than anything". And there are a number of things - provocative actions, for example, from North Korea would not be received well. "Clearly, the ballistic missiles program, as with Iran, with the intention of being a delivery system for nuclear weapons - that's gotta go".
Journalists asked Pompeo what such a denuclearization would look like and if it meant carrying out inspections in North Korean nuclear plants. Many traits originating before the 1950s remained shared, but while much of the art and music in South Korea over the last 65 or so years would be considered global in nature, North Korea embraced a self-sufficient philosophy and produced most of its own. They will frame Trump's willingness to meet Kim as a welcome first step along the road to denuclearization; and they will return the gesture with some corresponding concession, such as a freeze on testing nuclear weapons or long-range missiles.
North and South Korea affirmed their commitment to the goal of denuclearisation of the peninsula at summit last month, and Pyongyang announced at the weekend it will destroy its only known nuclear test site next week. "If he doesn't see material progress to that, there's not going to be a deal for a deal's sake", she said.
Drawn to big moments and bigger headlines, Trump views the North Korea summit as a legacy-maker for him, believing that the combustible combination of his bombast and charm already has led to warmer relations between North and South.
But Mr Trump's rationale for withdrawal from the Iran deal - it was "defective at its core" because it failed to solve every problem with Iran - establishes a test that Mr Trump will fail in his talks with Mr Kim.
