Our history books imply that the war was started with the steamrolling of France. That is incorrect.
Really? Please provide some evidence of this to support your claim. I don't read a lot of WW II history books these days (almost never), but I've read quite a few over the years. I can't remember a history book that I ever read which indicated or implied that WW II "was started with the steamrolling of France."
History books that I've read generally list the following as being the actions that started WW II:
1. the German Anschluss
2. the Treaty of Munich
3. German invasion of Czechoslovakia (which directly contradicted what Hitler had claimed during the negotiations for the Treaty of Munich)
4. the Molotov-Ribbentrop Pact between Germany and Russia
5. Germany invades Poland
6. Britain and France declare war on Germany, but provide Poland with little to no assistance
7. Russia invades Poland
8. Germany invades Denmark and Norway
9. Germany invades Holland and Belgium
10. Germany invades Luxembourg and France
So that's 9 major steps that took place before German forces invaded and defeated France.
Again, while I don't read many WW II history books these days, I think you'd be hard pressed to find any such book that states or implies that WW II started with the invasion and defeat of France by Germany.
