That's ok. We never made mistake, so we have nothing to repeat. Unlike our"Oh, look, why don't we give the #### the raw material and space to devellop a gigantic army" friends.
It is not one's own mistakes that one repeats. Of note, Hitler made the same mistake as Napoleon did so many years before him, a delightfully ironic mistake considering how much he wanted himself to be seen as Napoleon's predecessor: underestimating our lovely Russian winter.
Also, I seem to remember that a certain nation supplied us with shiny new war machines aplenty when we made the above-mentioned ####s pay for their treachery.
