Why not pluck boulders from space and toss them at your enemies? You hurl a big enough rock at a city and you have all of the effects of a high yield nuke without all of that messy radiation to deal with.

Actually it would not be that hard to do with a near earth asteroid. You could actually steer a "planet killer" at the earth. If you "push" the asteroid slightly when it is far out in its orbit it would not take a great deal of energy to put it on a trajectory to impact the earth. A 5 kilometer asteroid would do us all in.

Tungsten darts the size of telephone poles fired from the surface of the moon with rail guns would be formidable weapons. Maybe small rockets attached to make minor course adjustments.

We need to achieve the high ground.
