Churchill must integrate Japan without excluding America

Japan's proposed entry creates a diplomatic and coalition-command problem for Britain. Churchill would need to establish what Tokyo wanted and how Japanese units would operate with British forces. In this scenario, Japan seeks time to strengthen its forces and influence over a postwar division of spheres of influence. A meeting at Cairo or Alexandria could bring Churchill and Yonai together with Free Allied leaders and a senior American representative. American participation would make the talks more open and leave a route into the broader alliance. Britain's immediate need for military help would therefore have to be managed alongside American concern about exclusion from a future settlement.
