Britain, Japan, and the United States are treated as the three leading naval powers, with no overwhelmingly stronger mediator able to impose a settlement. Racial stereotypes and the sense of national affront would narrow the political room for compromise. The 1982 Falklands War supplies the comparison: American shuttle diplomacy failed to stop the fighting once gunfire, casualties, and sovereignty raised the stakes. Britain had also prepared for an eastern war through the Singapore strategy, so this would not be an unfamiliar contingency. That planning is traced to John Jellicoe's postwar imperial tour and was meant to draw on the Indian Army and wider imperial resources.
