Every time I read of this light novel in the back of my head it keeps reminding me of the Imperial Japan ideal of the "Greater East Asia Co-Prosperity Sphere" also written in casual speech as "Asia is for the Asians". See: https://en.wikipedia.org/wiki/Greater_East_Asia_Co-Prosperity_Sphere
The way Souma keeps going on wars and feels "forced" to go into war is a rather interesting imperialist thinking process. Also how they mention several times how it's a country where all these different varieties of non-humans and religions can co-exist. It feels vary much like Imperial Japan and how they wanted all Asians to to be grouped together in one massive (of course Japanese controlled) area. Though I guess there is no imperial west that Souma is saving anyone from.
It's still a fun novel but it's interesting to think about.
