I want to take over the world

What's the place on earth nobody wants to claim as theirs? It's not Ohio, it's a little region called Bir Tawil, on the border between Egypt and Sudan. The issue is that it's adjacent to a disputed region called the Hala'ib triangle, which is rich in... minerals and stuff. Thanks to a weird quirk of topography, the group which would own Bir Tawil would also not have a claim to the Hala'ib triangle. So, nobody wants it.

So, I beg of you, Egypt and Sudan; please let me have it. I'll take good care of it. I promise I won't use it as my base of operations for my inevitable supervillainry.

Apparently, the moon and other celestial bodies are also Terra Nullius, places not claimed by any state. I think I'd rather use the moon for my super-villain schemes, but I've got to start somewhere.

Thanks Wikipedia!
