And remember that after the invasion of Poland (which was a "staged" incident) Britain and France declared war on Germany. Not the other way around....
There were only small border skirmishes for a while until Germany invaded France BUT in the German mindset THEY declared war on them.
If you can try to read some papers from the actual time period and read what they actually wrote in the dailys back then. Highly interesting and you get a great perspective about what the average person/newspaper guys knew back then.
One of my favorites is the day the first atomic bomb was dropped. Headline was something like "Atomic Bomb dropped: Size of a Pea harnesses power of 1,000,000 regular bombs" and then they speculated about it.
Remember, only through history books and the information from all sides do we know "The rest of the story"... The average person had NO way of doing so...
