This should probably be considered in the larger thesis that the entire conflict was managed behind the scenes (guess who by?). The immediate context was a period known as the Phoney War.

This 8-month-long period was a big plot hole in the script, which is why few are familiar with it and it's never discussed. Poland at that time had been run by a military junta for decades. The UK and France gave Poland a military guarantee for no discernible reason (except maybe loving military juntas?).

"Smart" conventional historians would say that Poland was a tripwire, because the UK and France were waiting for war. Oh really? Because when Poland actually gets invaded by Germany, the UK and France do nothing.

It will only begin to make sense when you throw out all the "sense" conventional historians try to make about it.
