The amount of White sacrifice it would take right now to kill every non-White that ever exists, even simply the ones in our nations, would be too high to be realistically achievable. The more logical solution, though less ideal, is to expel all non-Whites back to their lands or execute those that resist. Yes it would be ideal to just kill them all, but the White lives cost to do that right now until we build our numbers back up is too high.
