imagine going back 1000 years and instituting a prime directive
and no white person ever visits africa or asia
we of course rape and kill everyone in americas and australia and make them 100% european
but we leave all africa and asia alone
and then just send camouflaged drones over to look at their backwards asses
A WORLD ZOO - and no population booms
at which point in history would it have been possible for all european powers to join forces and basically kill every asian and every african?
