Nuclear-tinged threats. Name-calling. Missiles flying over Japan.
Absent a detailed historical record and corroborating witnesses, the president's interlocutor could potentially leave the meeting and misrepresent what transpired, creating a he-said-he-said showdown that could turn into a major headache for the US leader.
DPRK stands for the North's formal name, the Democratic People's Republic of Korea.
The other countries at the G-7 summit, however, rallied to Mr. Trudeau's support.
A chief nuclear strategist for decades, he authored the letter responding to Trump's decision to cancel the summit, saying North Korea was still willing "to sit down face-to-face with the US and resolve issues anytime and in any format".
He said the U.S. would be satisfied with nothing less than the complete, verifiable and irreversible denuclearisation of the Korean peninsula - with verification the key part of any deal.
He would not say whether that included the possibility of withdrawing USA troops from the Korean Peninsula, but stressed the context of the discussions was "radically different than ever before".
The US president successfully sought to tighten United Nations sanctions on the North, and to get its traditional ally, China, to go along.
Trump is expected to arrive at 8pm local time (2200 AEST) and go straight to his hotel, the Shangri-La, the White House said.
On the eve of Mr. Trump's meeting with Mr. Kim, one of the president's top trade advisers, Peter Navarro, said there was "a special place in hell" for leaders like Mr. Trudeau, accusing him of engaging in "bad-faith diplomacy" with Mr. Trump.
Trump has said he hopes to make a legacy-defining deal for the North to give up its nuclear weapons, though he has recently sought to minimize expectations, saying additional meetings may be necessary.
At issue is whether Kim would be willing to abandon a nuclear weapons program that has advanced rapidly in recent years, posing an increasing threat to the USA and its allies.
Even White House press secretary Sarah Sanders has been forced to acknowledge, multiple times, that information she received from Trump and relayed to the public has not been correct. He credits his administration's "maximum pressure" campaign with getting Kim to the table.
Asked if he would meet Kim in Singapore, the ex-basketball player said he thinks the North Korean leader "has bigger things to worry about than seeing me right now".
Upon his arrival in Singapore, Rodman told reporters he wasn't sure if he would meet Kim.
"I am on my way to Singapore where we have a chance to achieve a truly wonderful result for North Korea and the World".
Still, the USA is not necessarily expecting to get a final deal in Singapore. "We now know they have a pretty good track record in these negotiations - a flawless track record of cheating every time, so that's the context we now face". "This is not the fault of either Trump or Kim, but rather a reflection that intractable, decades-long strategic challenges rarely-if ever-get resolved in single encounters", Haas writes.
The president has said that he would be willing to guarantee the safety of Kim's regime - though it's not clear how he would back that up.
In an interview with BBC (who really got our geography wrong yesterday), Minister of Foreign Affairs Vivian Balakrishnan confirmed what everyone was guessing a week ago: Singapore is indeed picking up the hotel tab for the North Korean contingent here. The North has faced diplomatic and economic sanctions over its nuclear and ballistic weapons programs.
He insisted the USA would accept nothing less than complete denuclearisation.
Pompeo's firm line on sanctions relief suggests that the United States is looking for a short transition toward denuclearization, according to Zhang Baohui, director of the Centre for Asian Pacific Studies at Lingnan University in Hong Kong.
