@Wormwood In general, the most militarily exceptional civilizations are also the ones with the strongest obsession for things like slice of life anime, being nice to their neighbors, and cuteness in general. We've all seen those pictures of Nazi stormtroopers hanging out with the little kitty cats they found, and modern Slavs have a disproportionate affinity for cat memes. Anglos conquered a pretty good chunk of the planet, and they're some of the most conflict-averse people alive.

In general, if all you've got is nogs with spears, you can pose and play at war as much as you want, and nothing will really happen. A few guys get scratches, the she-nogs think they're badass for getting scratched up, the circle of life continues. If you've got people who can build something like Imperial Japan, the British Empire, or the German, Russian, and American 'empires' during and after WWII respectively, starting a fight is much, much more costly for everyone involved. Sailer's Law applies on both micro and macro scales.

Christianity resonated with the West for this reason. A core theme was "be fearless when you have to fight, but turn the other cheek in needless spats". A good philosophy for dangerous peoples who live around other dangerous peoples.
