I discern that Full Disclosure is evidently missing the cooperation of the Aliens themselves -and that it might be that No Amount Of Publicity Or Calls For Disclosure will make any difference because they realize we are far too eager to fight as a planet. Humans are a juvenile race, it seems.
In other words, we might need world peace before they land in front of the UN. So, I think about 'how could we get world peace with all these problems?' Korea is a big one and the post above makes me think the Norks would be better off as a province of China. South Korea might wake up and conclude the same.
If Mama China was willing to take them in they would have done it 50 years ago. I don't think they want them either. Most of the business is done with the South anyways. Bringing in the North would just be a big bill to pay. Besides with the DMZ being there, North Korea is a good buffer state between the USA and China. I think all sides like that part of it. Otherwise it would be like the US and China sharred a boarder. The US would have to leave the South 100% and I doubt if they would ever do that on their own.
