Thanks, now I understand better.

Not as wacko a theory as I got the impression of. But not anything very new either. I don't know about actual historians, but I've always kind of thought if Hitler didn't start a world war Stalin would. Would be interesting if its possible to prove it and find the extent of soviet plans, but I'll try to keep a sceptic for now (especially as i can't read the german article

This part led me to believe the theory states Hitler knew about the plans of the soviets. So if Hitler only realised this threat after invading Poland (or not at all), I don't really see how it changes anything with regards to the necessity of invading USSR.As a conclusion it is also claimed that Hitler saw himself forced to carry out this attack in order to at least have a slight chance in fighting off the USSR.
