A French-style carrier system spreading across Europe

The French design path leads into a European carrier counterfactual. German, Italian, and Soviet projects could all have adopted a French-influenced system, giving four of seven carrier-operating navies a common lineage. Britain, the United States, and Japan would probably still each have fielded more carriers than the French-system navies combined. The scenario creates possible carrier contests in the Baltic and Mediterranean, while a Soviet carrier gives Japan a stronger argument for its own construction. A joke about the three established carrier powers uniting against the other navies is explicitly facetious. A French-derived design lineage could still reshape threat perceptions even if it never dominated fleet numbers.
