A surviving Singapore-based fleet would give the Allies a British-led concentration on one side of the Pacific alongside the American-led force on the other. Even delaying Singapore's fall by four or five months could give the British Indian Army more time to organise and make the Burma campaign smaller or very different. In this scenario, reduced Japanese access to the Indian Ocean could remove the need for the Madagascar invasion and large reinforcements to British East Africa. African troops who later served effectively under Slim might then reach Burma earlier. One objection is Burma's poor infrastructure, answered by the possibility of keeping Bay of Bengal shipping and ports such as Calcutta and Rangoon available. The Japanese advance is portrayed as logistically fragile enough that a rebuff at Singapore, supported by capital-ship gunfire, could leave experienced troops facing disease or starvation. These outcomes depend on the counterfactual Allied position holding long enough to assemble the additional forces.

If Force Z helped hold Singapore, the panel argues that the Allies could redirect reinforcements and keep shipping routes open while Japan struggled to sustain its advance.
