This situation cannot be compared to WWII, imo.
D'Hara has a bunch of friends and allies on all sides of the wars that were raging on, and still do. Some of these were against others, some of these were against each other. Luria Nova, on the other side, was allied with nations who were allied to realms that ended up declaring war on them (FR). One could not simply make up a list of involved realms and class them into two categories. Each nation has their own regional interests and continental interests, which often are in contradiction.
