For the United States, the Pacific was a broad defensive moat backed by a continental economy. Its homeland industry and exempt positions gave it reinforcement options that the treaty freeze did not erase. Britain operated at much greater distance but retained the ability to improve Singapore and other blocking positions. Japan, by contrast, was limited both in fleet tonnage and in its ability to build defense in depth across nearby islands, making formally shared restrictions strategically asymmetric.

Geography made the Pacific freeze unequal
The same status-quo rule burdened Japan more heavily because the United States had a continental industrial base and Britain could strengthen Singapore outside the restricted area.
