That is a beautiful quote by Orwell, who had a knack for getting at the essence of things. But I would disagree with the notion that one society should only adopt a belief if it generalizes to the entire planet. That's not really a useful yardstick to judge feasibility in a world that requires heterogeneity and in which different groups have different pressures. Universalism is a bigger lie than pacifism. So what role does pacifism play? Let's reinterpret the Orwell quote -- those who have money and guns can be Pacifists. I would say yes. If they were militarists, it would end badly as you would get powerful warmongering states. So a bias towards pacifism among those who strong and in no danger makes sense, just as a bias towards militarism among those who are weaker and in danger makes a lot of sense. Then we can look at the other aspect. If you are a radically different subgroup embedded in a larger population, you want to keep your head down. You don't want to be seen as a threat. So the Amish, famously apolitical and non-militaristic, are more tolerated by the rest of society.
