Great idea.. but one little problem. Finding a chunk of land that someone hasn't already claimed is going to be a bit of an issue; especially one with a port, which is pretty vital to the success of a nation.
Unless you're thinking Antarctica, or until we can get $399 one-way tickets to Mars (luggage & in-flight snacks included), we're SOL.
Until then, we in the US are going to have to keep fighting to take our country BACK.
