Tweeting from his hotel room in the pre-dawn hours on Tuesday, Trump sought to heighten the suspense.
He continued: "But in the end, that doesn't matter".
"I also think I'll know whether or not it will happen fast.it may not". But on the eve of the summit, he altered his schedule, opting to return at about 8 p.m. on Tuesday after a full day of meetings with Kim - nearly 15 hours earlier than previously anticipated.
Given the importance surrounding the on-again, off-again, and back on-again meeting between these two, it's hard to foresee what possible support that Rodman could offer these leaders in their high-wire negotiations. Kim is hoping Trump will relieve the economic sanctions that have crippled the North Korean economy.
Kim has offered to deal away his nuclear arsenal but doubts remain over whether he is truly willing to give up his nukes or is using the summit to weaken US-led sanctions against his country. On a larger level, the astronomical cost of the nuclear weapons program contributes to the massive poverty in North Korea, among the world's poorest countries. Trump said last week that Rodman had not been invited to the summit.
"I've been trying to tell Donald since day one: 'Come talk to me, man, '" he told The Guardian in December. He was originally scheduled to leave on Wednesday. In fact, only hours before the White House announcement, U.S. Secretary of State Mike Pompeo had seemed to lower expectations for the meeting, which Trump had earlier predicted could potentially yield an on-the-spot deal to end the Korean War.
Yet Trump and Kim have yet to agree even on how to define denuclearization of the Korean peninsula - the stated goal of the meeting.
The sudden change in schedule added to a dizzying few days for foreign policy for Trump, who shocked U.S. allies over the weekend when he used a meeting of the Group of 7 industrialised economies in Canada to alienate America's closest friends in the West.
"The idea is to force North Korea to do a quick and complete denuclearisation and not to drag it out, which will make the United States look like a fool", Zhang said "The problem here is: will Kim accept this?"
The Trump administration's desire for a win "increases the chances that this goes forward", Wagar adds. It was an extraordinarily compressed timeline for the landmark summit, one that left aides scrambling to initiate communication with the hermit nation. Today, we start with a behind the scenes of the summit. The Worm has visited North Korea on multiple occasions and competed on Celebrity Apprentice in 2013. The North Korean autocrat's every move will be followed by 3,000 journalists up until he shakes hands with Trump.
Still, the road to the Singapore talks has been far from smooth.
More than 2,500 journalists have convened here, with each leader's every movement tracked carefully.
South Korea's Hankook Ilbo reported that Singapore recommended the St Regis, which hosted Chinese President Xi Jinping during his 2015 summit with Taiwanese President Ma Ying-jeou, because it can be easily secured.
