Humm, my previous post responding to this was deleted, so lets do it again:
This explains why Hitler already had an agreement with Stalin to carve Poland up and why he had already positioned his army on the border to invade.
The above is a pathetic attempt to rewrite history, and only someone more pathetic and downright stupid would fall for it.
What are you talking about?
Britain extended the polish borders into german territory as a result of ww1. The polish then took the germans in that area prisoner built concentration camps and in the process massacred 50,000 of those prisoners.
Hitler wanted back what belonged to germany in the eyes of the germanpeople.
