What the heck are you talking about? We didn't have the "under-the-desk" drills, but we were painfully aware of how dangerous the USSR was. We felt sorry for the people subjected to such hideous political persecution, and the harsh standard of living and suppression of religion was just unbelievable. Finding out Russia was our ally in WWII blew our minds. We learned all about West Germany (and to tell you the truth, it still sounds odd to hear plain old "Germany") and the Berlin Wall and saw the films of people getting shot trying to escape East Berlin. I told my classmates my grandfather was born in Germany, not Russia, because of the stigma attached. (He was born where there was a large settlement of German immigrants, and his family came to the States later.) To hear about Hitler and his generals, the Gestapo & the SS, the concentration camps and millions of deaths was heartbreaking. Every kid in our school was of German descent (some still spoke it at home) and we couldn't believe we shared the gene pool with these people.
As for the communist military, that is what we trained for when I joined the Army. Everything was geared toward battling the reds. We were astounded that they had 2-year compulsory service, and that they trained with live chemical agents. We had a healthy respect for them, and we came out of training with a new appreciation for the freedoms we have in this country.
