I happened upon this video on YouTube and found it to be interesting on several levels. There is no way to fully show the depths of mental and emotional damage the ravages of war brings to a population but, in this film, you will see the horrible physical damage war brings to a people. You will also see people in the dress of the day, vintage automobiles (probably used mostly by people in high positions), modes of transportation for the masses, playing children who knew no other world than that of a nation in ruins, buildings/structures of interest that no longer exist, and a map showing the post-war division of Germany. In general you will see, in film, the infant progress of a resilient people accepting the devastating results of and turning their backs to the evil philosophy of a past government and, with the assistance of other nations, rebuilding from the ashes of a war-torn landscape to present-day Germany.
I believe that every upcoming generation needs to be shown the results of mistakes made by previous generations in hopes that those mistakes will not be repeated (in the near future, anyway).
