This article is about the fictional conflict found in the Southern Victory series. For other uses, see Pacific War. The Pacific War was fought between the United States and Japan from 1932-1934. It was a logical outgrowth of the aftermath of the Great War. The victorious United States had expanded its territorial holdings into the Pacific with the annexation of the Sandwich Islands. Japan, while aligned with the defeated Entente, had lost no territory, and was itself expanding its empire. One notable fact about the Pacific War is that it saw the first over-the-horizon naval battle.
