Please, I'm having enough trouble explaining the obvious strategic value of a moon base with nuclear weapons without introducing modified rail gun technology. It would be too much for some to digest, let me fight one battle at a time.
Chinese man go to moon.
Chinese man lift big rock. Oh, not so heavy as on earth.
Chinese man throw big rock at earth .
Rock fall faster and faster, like bullet.
Big boom-boom. Boom-boom very bad thing. No more Pizza Hut, no more Red Box video, even welfare place blown away to nothing.
Chinese man goes, wow. Chinese astronaut friend say, do it again. Chinese boss on radio say please don't hit China.
But then mormon MoonQuakers catch them and make them open chinese restaurant, they tired of eating moon rocks. MoonQuakers save Earth.
THE END ;^)
