brute strength works if you just need to fly an asteroid into the planet and everyone left behind is a bunch of mongrelized shitjeets that fell back into the iron age while you were out in space. the plan would be to use technology to escape this planet as well as to identify superior breeding stock to take to the off-world habitat. create the break away civilization. then when our numbers are around 1 million or so, we just exterminate everyone left back on earth, which shouldn't be hard because the way things are going people on earth are going to fail to keep their populations this high for much longer.
