“Springtime....for Stalin....in Leningrad....”
Heck when I was in the fourth grade (1957) we Army brats were comparing our dads’ Nazi war souvenirs. I thought the swastika was a kind of cool emblem & that the Wehrmacht had the snazziest uniforms in the whole war. One kid brought a German helmet to class, another a Luftwaffe dagger (!), all kinds of neat stuff. Go to someone’s house & handle Lugers and P-38 pistols.
Then one day Dad took me aside & explained just what the Nazis did to people who happened to be Jewish. Told me about a place he helped liberate called Dachau.
That was the first time I experienced pure horror. These kids need to be made to read Solzhenitsyn. They haven’t a clue about communism which lasted much much longer than the Nazi era.
