Madness........There's nothing to learn from that,maybe just how a nation can go full retard.Ok,you apologised for the Nazis but no matter how bad the Nazis were you just can't celebrate your country getting beaten to a pulp.Liberation ? Their cities were leveled to the ground,hoards of Bolsheviks raped every female they laid their dirty pawns on from 5 to 90 year old,women commited suicide after mass rapes,their scientific advancements were stolen so other nations could become "premiere space travelling nations".And you celebrate all of this ?...........
