The Moon is a Harsh Mistress.
A luna-Earth war would not simply be defending luna.
The effects of a 250,000 mile gravity assist should not be under estimated.
But the ultimate aailable high ground should not be overlooked.
If it is humanly possible, NASA must be gotten off of its ass, and we need to return to luna in force.
If we need a corporate front to do it, so be it.
