What are the possible scenarios had the Nazis successfully invaded Britain in 1940?
What about the impact on Europe as a whole?
If the Nazis had successfully invaded Britain in 1940, it's likely that the United States would have joined World War II sooner, and the war would have ended much sooner. Europe as a whole would have also experienced a different outcome, with a larger portion of the continent being under Nazi control.
