Here is a fine TIMELINE documentary, claiming that Germany accepted its humiliating defeat in World War I unnecessarily.
That the surrender could have been done with more honor, which would have been better for the whole world. And that Germany's general, Von Ludendorff, was for the last two years of the war essentially a military dictator. And although brilliant and patriotic, he was under such great stress that he was not thinking clearly, he was out of touch with the horrors of the war and saw the war through the pins on the map. That is, until he saw the slain body of his beloved stepson...and then he was devastated...again, affecting his decision-making.
I was thinking of Tink for this question, because of her thorough knowledge of German history and culture. But everyone invited/solicited to participate of course!
The problem is, of course, that WWI shaped so much of our history, even into the present day. And there is one comment under this YouTube video suggesting there are other interpretations of what was going on, other than this one from TIMELINE.
