They don’t need to (and can’t, unless they want a larger version of Zimbabwe). They’ll simply continuing stripping rights (via affirmative action in college admissions, jobs, government contracts, etc.) and whites will continue in their role of administering a welfare state designed to give large unassimilated blocs of our population everything for free.
One of my sons asked me, when feral blacks were looting on TV in Baltimore or Ferguson (all the same to me), why they did it; I responded that they did it because they knew white people would clean everything up and fix everything. The next morning, as if on cue, a white guy was flat-bedding a burned car out of the war zone.
Destruction isn’t the goal; serving the “victims” is. In any case, the number of worker bees is quickly dwindling as white guys refuse to breed; the replacements trafficked here from abroad don’t want to administer the welfare hive, but would rather simply take what they can from it.
It took the Catholic Church hundreds of years of propagandizing in Europe about the Jewish problem before the continent acted on it. It’s nothing different here and the results won’t be any different.
