Mr. Trump's actions led to an extraordinary juxtaposition: an abrupt public feud and deterioration of ties between the USA and Canada at the same moment as warm words and a detente between the US and North Korea.
North Korean dictator Kim Jong Un arrived in Singapore Sunday afternoon, while US President Donald Trump flew in hours later in the evening. He said he believes the USA wants the North to accept a "kind of capitulation model again".
Any nuclear deal will hinge on North Korea's willingness to allow unfettered outside inspections of the country's warheads and nuclear fuel, much of which is likely kept in a vast complex of underground facilities.
The president's rhetoric has not mirrored that of his new secretary of state.
Trump said last week that Rodman was not invited to the summit.
'Cheating Every Time' North Korea has previously promised to denuclearize, only to continue its nuclear program after receiving concessions from the USA, said Michael J. Green, senior vice president for Asia and Japan Chair at the Center for Strategic and International Studies.
On Monday, U.S. Secretary of State Mike Pompeo suggested U.S. sanctions and other worldwide pressure will continue until North Korea takes steps toward denuclearization.
He would not be drawn on what might be on offer.
Both sides also worked to finalize preparations for the unprecedented summit.
President Donald J. Trump will meet with North Korean leader Kim Jong Un tomorrow morning at 9:00 a.m.
Their first meeting will be just the two men, with their translators, without any advisers present.
'Challenging Path' "We could be on a course for a more collaborative approach and lower tensions, albeit in a very challenging path forward on the North Korean nuclear issues".
Choi Ho-chul, a 73-year-old former bank employee, said he doubts the North would give up nuclear weapons, which he said were a "means to control its population". The article titled 'Trump and Kim - The meeting the world's been waiting for' also noted one subject that went untouched by other media houses - "What will nearly certainly NOT be talked about is North Korea's human rights record".
A CNN analyst, in a report titled 'Four steps for a successful Trump-Kim summit', highlights how "it is still hard to predict how any summit will go (especially with two unpredictable leaders such as Trump and Kim)". "I'm unconcerned about our capacity to continue to do what we need to do".
So how should Trump communicate with Kim?
For decades the United States has been a sworn enemy. There are even anti-American museums in Pyongyang. And that was some of its milder language. It heralded the summit as part of a "changed era".
In part, these lowered expectations are a reflection of the extreme skepticism among many that the North can be persuaded to give up a nuclear programme it has stubbornly built over the decades, often in secrecy and despite intense sanctions, global condemnation and widespread suffering among its people. "I feel that Kim Jong Un wants to do something great for his people and he has that opportunity".
This is just an elaborate get-to-know-you session, albeit between the two most famous leaders in the world, and nuclear armed at that.
Many experts on North Korea, one of the most insular and unpredictable countries in the world, remain skeptical Kim will ever completely abandon nuclear weapons. "We're not going to go in and sign something on June 12, and we never were".
It's not a matter of giving or denying Trump "credit" for the meeting but about results, Wagar said.
Denuclearisation has been the central issue in the run-up to the talks.
The North Koreans did not seem keen to be interviewed or photographed, however. The question is what concessions he is willing to make, and whether he will stick to any promises made.
Still, the U.S. is not necessarily expecting to get a final deal in Singapore. "He's not kidding when he says this and he will walk away ... and I believe that Kim is smart enough to know that".
