The 21st Century Version of the Outer Space Treaty

We need a 21st century version of the outer space treaty, I think. Most people have signed up to the idea that we won't have weapons of mass destruction in space. So there's nothing to say I can't put a laser on my satellite. And if we did all agree not to do that, then we could diminish the arms race. We've established what the rules of earth are, now you have to establish the rules of everything outside of earth.
