I seem to recall one of the variant's in Avalon Hill's classic Third Reich boardgame to be, "More commitment from the Empire" for Britain. Now, in real history, what would this mean? The Aussies sticking around Europe instead of the Pacific? Or something more?
Would it have been possible to mobilize even more of the manpower and resources of India then was OTL? Could Canada have realized one of her occasional, almost secret ambitions and built a massive warfleet?
Or is all this half-baked?
