Winning a total war : its about building a Big Tent of all possible talent, not in draining down your gene pool

Early to mid September 1940 were undoubtably the darkest weeks of WWII.

Britain awaited an air assault followed by a sea invasion by a all-powerful German war machine that was backed by Russia, Italy and Japan along with a host of quasi fascist fellow travellers among the nominally neutral nations.

There was no Big Tent of all possible talents assembled to help Britain, or any of the dozen or so smaller nations who had already fallen, equally alone and isolated, to the Axis powers.

Britain was as guilty in all of this as any nation - for it too failed to build itself a Big Tent internally, to take advantage of its empire's overwhelming demographic superiority over all the Axis powers combined.
