Physics for the aggressive minded

There have been repeated calls from the hawks to weaponize space and create orbiting bombardment platforms to 'maintain US space and land superiority...' - well... other than being a really bad idea - there is that pesky problem of physics... perhaps you've heard of it.... I'm sure somehow you'll get more funding from my tax dollars to persue this type of crazy scheme with no hope of success (and claim you are making me safer somehow...) meanwhile the science budget is getting hacked to bits and the space exploration budget is grossly under funded...
