Securing the Confederate’s Foundation
The war in the pacific was very chaotic.
The sudden war that occurred underwater did very little to alter the peace between the ships at the border.
The WGP had issued that while submarines inside the border regions may fire and attack each other, the ships out of the border weren't allowed.
The logic behind this was that submarines were ordered to stay at a certain depth so that any ranged attacks it would fire were easy to intercept. As the WGP were rulers in underwater warfare, the only option for the submarines could attack the WGP was over the waters.
The WGP could track and observe any attacks or torpedoes these submarines would launch and where they would go.
But the ships that were above sea level could not fire any long or mid-ranged weapons. Violating it would force an Emperor to step out and massacre the fleet.
