Infinity - Yu Jing White Banner Expansion Pack Beta

It's often said that PanOceania is number one, the Hyperpower. Is it? Are you sure? If that's so, if they truly are the strongest power in the entire Human Sphere, then how was half of Svalarheima taken away from them? How is it possible that after so much time, after so much overt and covert fighting, they still haven't recovered it yet? Both questions have the same answer: the White Banner Army.
