Britain, France, and Italy's 1940 coal problem

Why did Britain fail to appreciate Italy's coal-supply problem in 1940?

Britain was prioritizing its own and France's wartime coal needs, creating pressure on Italy's external supply even though the precise policy context requires more research.

Britain was purchasing coal for domestic and allied requirements while French mining regions faced combat and mobilization. French demand rose as threatened mines closed or lost workers, and British miners also volunteered before all of them were protected from enlistment. Blocking German coal shipped through neutral ports was legitimate wartime trade interdiction, but it sharply constrained Italy's external supply. The panel cautions that the referenced argument needs fuller context and doubts that railways could replace the maritime quantities Italy required.
