Thank's for sharing this Intel. It makes perfect sense,after watching both videos you suggested, that this information was withheld, and purposely blended with misinformation by the CIA, to hide their own preparations for dealing with this global catastrophe. If there are large cities that have been built underground, and are connected to each other with tunnels, they can only hold so many people. This would also explain the huge black budget money that no one seems able to explain. If they can succeed in being the first generation of people that survives intact with their technological knowledge, than I can see mankind reaching the stars before the next global catastrophe. Two points though: these will not be the best of our species as far as moral character goes, and they will all probably be crushed when the Earth's crust displaces.
