Saying that the clans were mongol horde redux is an insult to the mongols
Nuking the amount of worlds they did isn't exactly that much of a stretch if you think about it, you don't actually have to nuke everything just the major areas then the fallout and sunblockage will generally kill off the stragglers, and well at cold war era we built quite enough to wipe out multiple "earths" even with our antiquated (by bt standards) industrial and nuclear tech. Also that WOB spinal mounted mass driver newgrange warship could pretty much do everything by itself since it had more than enough ammo because it just used asteroids (and only needed a few shots per world).
