I have used weapons in Outer Space. While these days at 72 years of age I'm watching TV, in years past I have fired nuke tipped missiles at the incoming Comet Elenin. While firing at Elenin Saucers appeared from the back of Elenin. I took them out with a Directed Energy Weapon.
I know that stealthed missiles have proven somewhat capable in Outer Space. But America, and Earth, have a long way to go before it can deal with the Space Forces of Civilizations that have been in Outer Space for thousands of years!
When I said that 'War In Outer Space' is coming I know that with thousands of Alien Civilizations it just a matter of time. In fact, it's already here! The bottom 1% of Aliens are really something else. They're mean, vicious little monsters!
Look what they did to Space Shuttle Columbia:
And, Aliens were behind--as reported by Russia--a direct hit by Comet Elenin. So, we're already in it whether you like it or not!
Added Bonus: Comet Elenin 'mysteriously' breaking up!
So, take my word for it: SPACE WARFARE IS ALREADY HERE!
Just for fun--but it could happen any time!
