Dr. Barry Goodfield, who's profiled notorious dictators including Saddam Hussein, said failure is not an option for President Donald Trump and North Korea's Kim Jong Un during the historic summit on Tuesday.
While Trump was optimistic about prospects for the summit between the old foes, USA secretary of state Mike Pompeo injected a note of caution ahead of the first-ever meeting of sitting U.S. and North Korean leaders, saying it remained to be seen whether Kim was honest about his willingness to denuclearise. Its outcome could prove pivotal in determining whether the two nations pursue a lasting peace or a fresh military conflict.
Mr Kim and Mr Trump will finally come face to face at the Capella hotel on Sentosa, with both leaders looking to hammer out a deal that may lead to North Korea giving up its nuclear weapons programme in exchange for security guarantees. Would conventional politics have even taken us this far?
Goodfield added Trump should remain authentic.
It's "a sign of recognition that the North Koreans have sought for decades".
"The senior officials of the party and government sincerely wished Kim Jong Un good successes in the first summit meeting and talks between the DPRK and the United States and his safe return", the KCNA said. They will be joined only by translators and will spend a couple of hours before admitting their close advisers to the meeting.
Kim is now scheduled to leave Singapore around 2pm on Tuesday with Trump departing on Wednesday morning.
Kotani pointed to countries such as France and the United Kingdom, which say they have no plans to lift sanctions at this point, as the key to keeping pressure on the North.
But Mr Trump warned "he was prepared to walk away" if the summit did not go well.
"Why would Kim Jong Un insult me by calling me "old, ' when I would NEVER call him 'short and fat"?" he tweeted.

Kim has been more cryptic and calculating, with his regime vacillating between welcoming talks with the USA, ignoring American overtures, and sharply attacking some of Trump's top officials with insults and threats, said Patrick Cronin, director of the Center for a New America Security's Asia-Pacific security program.
Olivia Enos of the US -based Heritage Foundation is urging Trump to not ignore rights concerns.
In the 1990s and again the early 2000s, North Korea agreed to halt its nuclear program only to continue with clandestine research. He credits his administration's "maximum pressure" campaign with getting Kim to the table.
Trump and Kim are expected to meet at 9 a.m. Tuesday in Singapore, which is 9 p.m. Monday in NY.
However, it now appears that the U.S.is confident tings are going smoothly.
"We've had multiple deals with North Korea", said Green, who served as director of Asian affairs for the National Security Council under President George W. Bush.
Just a few months ago, Kim was an worldwide pariah accused of ordering the killing of his uncle, a half-brother and scores of officials suspected of disloyalty.
He added in addition to using bulletproof vehicles, North Korea's security detail would likely deploy layers of protection surrounding the summit venue and try to divert attention from Kim Jong Un's auto whenever he moves.
The US wants North Korea to give up its nuclear weapons but it is not clear what Pyongyang might want in return.
The North Korean autocrat's every move will be followed by 3,000 journalists who have converged on Singapore, and by gawkers around the world, up until he shakes hands with Trump on Tuesday.
