I heard the same thing about a problem heading to the International Court in the Hague about the UN claiming ownership of part of our border because of the national monuments being considered "UN land belonging to the citizens of the Earth" -- for most everyone in the US this sounds insane. However, there is all sorts of mischief moving everywhere just now.

The first is a petition against the UN for our land.
