"That's a good question".
Then Trump hit an assortment of topics, including trade, North Korea and kept pushing for reinstatement Russia, which had been tossed from what was then the G-8 in 2014, after the country annexed Crimea and endorsed pro-Russian separatists in Ukraine. But following a visit to the US from Kim Yong Chol, a top North Korean official, Mr. Trump confirmed the summit was back on.
"I was really disappointed to see President Trump just dismissed the idea of talking about human rights", says Kristof.
"It's a one time shot and I think it's going to work out very well", he said.
Trump and Kim are due to meet in Singapore on Tuesday.
Kim has the "opportunity the likes of which, almost, if you look into history, very few people have ever had", Trump said. "I think that Chairman Kim Jong Un is prepared to do that as well", he said. "It may not. [But] if I think it won't happen, I'm not going to waste my time and I don't to waste his", he said. "I don't want to waste his time", Trump said.
"We might see a similar scale of security personnel from North Korea and safety protocols as we did in April, but they'll also have help from Singapore like special vehicles and agents", said Cho Seong-ryoul, senior research fellow at the Institute for National Security Strategy. The president appeared exhausted and subdued, and he demeaned the press corps, calling some US news outlets "unbelievably dishonest" and "fake news" before aides pulled him away to start his journey to Southeast Asia.
Other major summits held in Geneva include the 1955 meeting of US, Soviet, British and French leaders, the 1985 summit between US President Ronald Reagan and the Soviet leader Mikhail Gorbachev, and the 1994 meeting between officials from Washington and North Korea that led to the signing of an accord to freeze and dismantle Pyongyang's fledging nuclear weapons programme.
"The people know these are all lies because it's obvious".
Trump has said he believes Kim would agree to denuclearization - and Secretary of State Mike Pompeo said Thursday he had received Kim's personal assurances to that effect - but the two countries have offered differing visions of what that would entail. But Lee and the other analysts pointed out that Libya hadn't developed nuclear weapons nor intercontinental ballistic missiles (ICBMs), and North Korea has both. "The haters, they say, "Oh, you're giving him a meeting" - gimme a break, OK?"
On rating G7 friendships: "I would say that the level of relationship is a 10".
Speaking today before he left the G7 summit in Canada and head to Singapore, Trump described the summit as a "mission of peace".
Mr Trump was able to portray North Korea's scramble to convince him to stay in the talks as a victory - but also to redefine the terms of the talks. President Trump can not fully suspend sanctions on North Korea unless North Korea agrees to key reforms.
"So we're going in with a very positive spirit", Trump said, before misidentifying the site of the meeting.
The diplomatic initiatives leading to the summit started in late April when Kim met South Korean President Moon Jae-in and the leaders of the rival states pledged to end hostility and establish peace on the Korean peninsula.
