When the British first arrived in America, they believed the Indians could be negotiated with. They tried to talk to them, convert them, to be reasonable. For that, they were punished with treachery and murder, and soon set about exterminating the Indians
They and the Europeans generally carried that attitude to Africa, where they were willing enough to let the natives keep managing their affairs, but never really forgot the importance of the Maxim gun and repeating rifle in dealing with such populations
Then the egalitarian strictures of the post-war era forced them to forget that, and to instead belief that not only are all men created equal, but they are all equally capable of being hardworking and generally law-abiding members of a semi-industrial society. Muhammed and Mobutu will make widgets and enjoy meat pies like everyone else!
But such is a lie, of course. Not only are men not equal, but some groups are far worse than others, and will either be taught to obey by the staccato of the Maxim gun or will never obey, and instead prey upon those who try to help them, out of whatever ridiculous and misguided instinct.
Such will have to be learned again, and the will to put that lesson into practice regained, for Europe to be Europe again
