There's a difference between sharing information and a river of glorification.

Not all the WWII history shows glorified it, but lots of them did and did often. I've heard too much about the brilliant tactical minds that ensured the fall of Nazi Germany and paved the way for democracy and freedom. Too many tank battles are called great, and not enough called tragic. Famines and desyruction of infrastructure ate often mentioned for their strategic effects, and rarely for the rapid destruction of society they cause.
