There's a thread dedicated to it now. 
https://www.resetera.com/threads/will-trump-get-a-nobel-peace-prize.38926/
Nobel prizes are all about optics.
After the meeting or perhaps at the meeting. Trump will invite Un and Moon to come golf at the Mar-a-lago.
They will laugh on camera and enjoy themselves over a luxurious dinner at this TRUMP(TM) property.
Trump will make some speech about having achieved world peace, makes a joke about North Korean labor camps, "Maybe we need them too, it's kinda wonderful that in your country everyone has a job" and shouts at reporters.
But even CNN has to admit that this is one great feat that President Trump has pulled off. If anyone doubts it, Moon of South Korea will once again thank Donald for his peace-making efforts and offers him a gift.
Trump will likely make Un so comfortable at the Mar-a-lago that he will plan regular visits to hang out with Trump, Kanye and playboy models of his choice.
Some sort of deal between Trump and Kim for economic aid will end with a shitty Trump hotel in the middle of Pyongyang that none of the starving citizens can afford.
On ResetEra a lost soul opens a new thread: "I will jump in front of a train if Donald Trump receives a Nobel Peace Prize tomorrow"
Let's be real here. The deal has already been made. It just needs to become official. Whatever offer was on the table has likely been discussed already between Kim and Pompeo.
There's no reason for Kim to suddenly cooperate with this adversaries and then walk away again because some expert on TV can't believe this is happening.
