The first proposed scenario sends Britain into war with Japan without other powers joining its side. Britain would then have to decide how much military and naval strength to divert east. That burden could reduce support for France and alter the response to German expansion in Eastern Europe. The idea is a counterfactual framework for tracing connected strategic choices, not a claim about what actually happened.
