It isn't very realistic for Britain to remain neutral in a World War II where Nazi Germany is involved. However, out of curiosity, I decided to ask about this hypothetical scenario:
How would France have fared in World War II had Britain stayed neutral but also had France had better generals during this time? In other words, while Britain stays neutral in this TL's World War II, France's military also has better leadership in 1939-1940 and thus keeps the French Seventh Army stationed at Rheims (as per the original plan) instead of sending it over to the Low Countries.
Also, France would still be able to purchase military equipment from Britain and the U.S. in this TL; indeed, it would simply have to fight Nazi Germany alone once Poland falls.
Anyway, what are your thoughts on this scenario? Would France be able to successfully blockade Nazi Germany by itself? Also, would France be able to overcome Nazi Germany's two-to-one advantage in population and defeat it?
