US claims space

Details of the US’s new space policy was released today.

To quote directly from the BBC:

“US President George W Bush has signed an order which asserts the US right to block access to space to any country or group deemed hostile to its interests.

The document says the US is determined to protect its interests in outer space and will defeat any adversary who threatens them.”

Now surely to control access to something and other users right to it, you have to own it.
