[Just mythoughts]

"Interesting post. Ages old questions. In keeping with the theme I could add "Why didn't God save his only begotten son from the cross?"

Christ as the final perfect sacrificial lamb was preordained, were it to have been prevented "save" would have been the Heavenly Father withdrawing his promised gift of salvation from all His children.

WWII did not happen in a vacuum there is a historical record that laid the foundation to follow how it was that a nation would follow a lunatic (Hitler) into the bowels of depravity.

I am of German decent my great-grandfather came to this nation as a stowaway in the late 1800's. He is a mystery, finding verification that his name here was in fact the name given to him at birth is like searching in a black hole.

I believe it was preordained, too. However, this also implies that those on Earth whom history regards as responsible for Jesus' death, were not really responsible for His death at all since it was meant to happen the way that it happened.

Chiefly, the hyper-inflation that occurred within the German economy after their nation was found [by the victorious alliance of nations] to be responsible for the destruction from WWI and made to pay reparations for that destruction.
