The moon is at the bottom of it's own rather deep gravity well. Landing equipment and men there is many times more expensive than putting them in low earth orbit. Returning mass from the moon takes about two thirds the delta v of just getting something into LEO from earth, and that fuel has to be shipped from earth, so another order of magnitude more expensive. That's why the Apollo lander returned so little mass. And moon projectiles take days to reach Earth, are easy to track and intercept. So no, putting kinetic projectiles in LEO is far cheaper, far more accurate, far harder to stop, and can hit targets within minutes. A Falcon Heavy could lift 100,000 lbs of "rods from god" with fuel to LEO for less than $150M. That would only get a few thousand pounds of equipment/fuel to the moon. The moon has no military value for Earth. Far too expensive, far too far away.
