ITTL, the Fashoda incident declined into a brief colonial war between France and Britain, and thusly French and British relations never recover. French conservatives, disgraced by the war, are ousted and replaced with the left wing. The Fashoda incident was the last serious colonial dispute between Britain and France in OTL - in TTL, it isn't.
With such a fundamental shift in British-French relations, would WWI develop as normal? If not, how would it change?
