I wasn't even alive.

My knowledge is acquired from documentaries and books discussing the time. If you want to deny that there wasn't a period of intense fear that the Russians would nuke us, go ahead. Propaganda and fear-mongering wasn't invented post 9-11.
You have to understand that the US had just emerged from WWII. Air Raid drills for the public were an accepted part of life. Our parents had been through them and nobody was terribly upset.
Air Raid shelters were all over the place. When the whistle blew, you just went to your designated shelter.
History books and documentaries overstate how scared the people were of a nuclear war. Yes, we were aware of what a nuclear bomb was....but as kids, we did not take it to be that big a deal
Well let's not exaggerate my initial comment to imply that I was referencing ALL children. I made a simple remark about some people sharing their experiences as a stressful time. As a teacher of first graders during 9-11, I know that my students had some questions in the days to follow. I'm sure some were also bombarded at home by parents who may have kept cable news on 24/7. We'll see how they reflect on all of it someday.
I can't tell if you're in agreement with those advocating that we live in a mindset of fear, or have learned to "accept" it, as you see your generation having done so. Do we have more or less tolerance for the radical Muslims than we did the "Commie bastards"?? I'm not sure, because the hate for Russians was still going strong in my childhood of the 70's and 80's.
