| Biggest mistake?
Germany starting the bloody thing. If they had waited for long enough, Stalin would have started it all by himself. The Germans would have rushed to the rescue of Poland, ther French and Bristish would likely had become involved and suddenly Fascisim would have been in bed with the Democracys.
Germany could have snaked into Russia, nicked al the land they wanted and would probably still be there today.
Certainly would have made for an inersting post war period |
