If Britain surrenders before Hitler starts Operation Barbarossa, does it succeed? Let's say as a POD Germany moves into Dunkirk and massacres all soldiers, allowing for a very big public opinion shift on war in the UK. The UK makes a white peace with Germany. If this scenario is unlikely, then choose any other possible TL in which Britain surrenders to the Nazis prior to Barbarossa. Now, on to the question, does Operation Barbarossa succeed, and do the Axis Powers win WW2 if the Nazis and Soviet Union are fighting only each other? Does Japan still bomb Pearl Harbor? How does the war turn out if there is no British Empire to oppose the Nazis?
