I am working on a TL where the UK secures a white peace with Nazi Germany in 1940 right before Dunkirk. In 1941 Germany invades the Soviet Union. Japan launches a similar attack on UK/USA/Netherlands in late 1941/early 1942. Germany (as in OTL) attempts to bring Japan into the war against the Soviets by declaring war on the USA, while the UK is still neutral. Japan (as in OTL) does not declare war on the USSR. With British neutrality, the USA can only skirmish with the Nazi’s in the Atlantic and maybe land in North Africa.
My question is how quickly does Japan lose when it has to contend with a UK and USA that are focused on it? Can the UK save Singapore and Hong Kong?
