World War II ended in ways Arthur had never imagined, but this did not influence Australasia's strategic layout before and after the war nor Arthur's vision for the future.
After the end of World War II, Australasia indisputably became the world's strongest country, especially following the grand parade of the tri-service military on the day of the United Nations assembly.
Representatives of various countries witnessed the potent forces of Australasia's army, navy, and air force, and they naturally understood who the most powerful nation in the world was and whose rule they should rely upon.
As for the former hegemon, the British Empire, Arthur did not eradicate them completely. If the British desired, they could still play the so-called European hegemon or even become the most powerful nation outside of Australasia.
Of course, as part of Arthur's plan, following the end of this World War, it was naturally also time for Arthur to bid farewell to the throne.
