The Hundred Years' War and choosing the correct counterfactual

How would Britain losing the Hundred Years' War affect the modern world?

England already lost the struggle to retain control of France. English victory and continued control of France would be the changed premise, with consequences too extensive for a firm modern prediction.

England failed to retain control of France, making the proposed loss the historical outcome. A loss alone therefore does not establish a new timeline. English victory and continued rule over France would create the major divergence. Predicting its modern consequences is judged too extensive because so many later events would change. Mary's later loss of Calais is distinguished from the earlier failure to retain France.
