The invitation was hand delivered on Saturday by Kim's sister, Kim Yo-jong, who is visiting the country for the Winter Olympics, as part of the most senior delegation from the North to visit the South since the Korean War in the 1950s.
What was lost to editing was no great loss, although USA viewers were deprived of a knowing chuckle from hearing International Olympic Committee President Thomas Bach thank the volunteers making the Pyeongchang Games go.
Mr. Kim relayed the invitation through his only sister and trusted adviser, Kim Yo-jong, who met with Mr. Moon at the presidential Blue House in Seoul on Saturday, in the highest-level contact between the two Koreas in years.
The Korea team, which featured three DPRK players (Kim Un Hyang, Jong Su Hyon and Hwang Chung Gum), nearly took an early lead when forward Han Soo-jin flicked a shot against the crossbar at the end of a breakaway move.
Pyongyang conducted its largest nuclear test a year ago and said it had developed a missile capable of carrying a warhead to the United States.
While a summit in Pyongyang would signal warming ties on the peninsula, it also risks driving a wedge in the alliance between the USA and South Korea.
Minutes later came a moment stunning in its optics and its implications: the United States, represented by Vice President Mike Pence, sitting a row ahead of Kim's sister, Kim Yo Jong, and the North's nominal head of state, all watching the games begin - officials from two nations that many worry have been on the brink of nuclear conflict. If peace isn't imminent, a summit in Pyongyang between Moon and Kim Jong Un seems better to most than the threats of recent months. Later Saturday night, they all joined the chief of the International Olympic Committee to watch the debut of the inter-Korean team in the women's ice hockey tournament.
Kylie Jenner's 'more mature' since becoming a mom
Between the name reveal and the image of Stormi's tiny hand, Twitter and Instagram have found enough material to work with. Hailey Baldwin thinks Kylie Jenner has handled her pregnancy in a really "mature" way.
"We have to put this in context in the spirit of the Olympics and why we're here".
The delegation will return to North Korea on Sunday. The other objective for Pence's appearance was to see Moon for a final time, forging one more photo op of the two, in light of the events of the day. The Swiss won 8-0.
But Moon, a liberal who has always wanted to engage the North, will also have to convince a good portion of his own people who are deeply wary about North Korean intentions. There were rumblings of discontent over having to drop players to add the North Koreans, and of being pawns in a game they did not want to play. He did not shake hands with Kim Yong Nam, they said.
"What we honestly don't know yet is why it is historic", Ramo said. The meeting would be the first official talks between the two in 10 years.
North and South Korea have shared a heavily fortified border since the Korean War ended in a ceasefire, not a peace treaty.
"I am open to any form of meeting, including a summit, if these are necessary to improve inter-Korean relations and resolve the North Korean nuclear issue", Moon told more than 200 reporters at the Blue House in January.
American luger Erin Hamlin said it was "too bad" that there was disappointment about her carrying the United States' flag at the Winter Olympics opening ceremony and that any athlete would have felt honored to accept the task. This was not supposed to be, as some in Seoul grumble, the "Pyongyang Games", a play on the North Korean capital's phonetic similarity to Pyeongchang.
