If it was up to me, I'd bring back something like the British Empire. I see non-whites as kind of like children and whites as adults. There can be individual smart children and dumb adults, but on the whole a village run by children is going to be a poorer and shittier place to live than a village run by adults.
Don't believe the Marxist frauds, non-white colonies prospered under liberal imperial rule. We stamped out the slave trade, suppressed crime and banditry, suppressed barbaric practices like widow burning, brought order, built the roads, the clinics, the schools, made the streets safe and the buses run on time. On that foundation we built economic prosperity. What happened when we handed these places over and left? Everything went to shit. Many non-whites are nostalgic for colonial rule. I mean, they emigrate so they can live in a country run by whites. If we ran their countries they wouldn't have to do that. It would solve the immigration problem.
