A pillar with a tiny engine that just incrementally increases the speed could be devastating at a distance though, I'm sure I've read this as some solution to a problem (or attempted solution to some problem) in some sci-fi book, can't remember which though.
But to me it really doesn't make more sense than using nukes though unless they are coming from another body in space, dropping shit from normal earth orbital altitudes is like throwing peanuts compared to something coming out of solar orbit, and actually hitting your target is 10,000x harder. And anyone with a space program large enough to put such weapons in place could more easily produce nukes instead.
