They want this ban because they know they cannot compete in the advanced technology necessary to make it work! The Soviets knew that Reagan's "Star Wars" could be built and that it would work. As a matter of fact every weapons expert in the world knew that it would work. Liberal democrats in congress said it would not work and proved once again that when it comes to the military and related activity they know nothing. It is an extremely advanced and expensive area to get into and they (Russia & China) cannot compete with the USA. I think we need to be able to have a very strong military capability in space. Why? Because we, meaning all mankind, really don't know for sure what is out there!
