The Risk of a Star Wars Type World

Is there a risk of a Star Wars type world where we're fighting outside in space, not so much weapons of mass destruction hitting Earth? Yes. I believe the satellites will be armed and it won't be too long in the future. The Russians have already tested a satellite which opened some aperture open. It fired something and no one's quite sure what at another one of its satellites. They fired something. So that genie is just about out of the bottle.
