Due to their relatively fractured homeworld, simply talking about 'human society' is almost meaningless. What is normal to somebody in the Blessed Mexican Empire is exceptional to somebody in Russia, and vice-versa. Communications and transport between the various nations is common enough that a citizen with enough money can chat leisurely with anyone from anywhere, but this has not spelled an end to human division or conflict. Still, warfare between the various nations is less common than once it was. Historical hotspots such as the Middle East and Ireland are, if not tranquil, at least not the infernos they once were.

Fortunately for humanity, the Russo-Chinese War of 2716-18 was the first major conflict for well over a century and, in spite of the two years of declared war, actual high-level fighting only took place for eight months. Since the war humanity has gained knowledge of faster-than-light travel and has become more and more aware of just how small they are compared to the other powers of the galaxy. Fortunately for humanity, therefore, even old enemies among the United Nations have begun grudgingly cooperating: the creation of Persephone itself was heralded as a great moment in international cooperation. Meanwhile, human space forces, while technically part of the militaries of the seperate nations, frequently work together and run maneuvers as a single unit, realising that the greater threat comes from outside rather than from within.

Of course, increased cooperation has not eliminated all rivalries. The Russians and the Chinese were two of the major partners with Persephone and disagreements between the two were common: this mutual distaste has often continued between the citizens of the two nations living on Persephone, driven together by circumstance and still remembering old grudges from a planet they may have left years ago.
