at school I pointed out that since we had 4 Air Force bases in the general area (two on the outskirts of our town) and also the Concord Weapons Station down south, in the event of a nuclear war we might just be grease spots within minutes of any alert. I recall that that comment did not go over well with my teacher. This was in the 1962/63 school year.
The Cuban Missle Crisis fit in with the sense, in my recollection, that the real possibility of nuclear holocaust hung over all of us. Popular fiction/films such as Seven Days in May, On the Beach, Dr. Strangelove were current in the early 60's. Much later, in the 80's, there was "Testament" on TV.
"MAD" threatened the world, but that was how we were supposedly supposed to maintain the "peace." And some folks argued about the survivability of thermonuclear war. (Here's an excerpt from Robert Scheer's "With Enough Shovels" from the Reagan years amazingly:

To this day, the last Friday of every month at 11:00 a.m. the sirens go off in my city, a monthly test. A holdover from the Cold War. They were to be the warning alert of an impending nuke attack. When frankly all you could do if you lived in an area that might be close to a target was to kiss your ass goodbye and pray. Now they're considered a general emergency warning system. I recall once in the mid 70's a friend from a rural area was in town when the monthly alert went off. She freaked and I had to explain to her what it was. It was so unusual to her and so normal to me. To me it was just a reminder it was the last Friday of the month. But I also remember how once when the damn things malfunctioned and went off not during the usual test time I was "WTF," wondering if something suddenly had gone very significantly wrong with the world.
Perhaps when we try to compare the peace/antiwar movement in the 60's/70's with the present, we forget the impact that the seemingly omnipresent threat of potential nuclear war had on the participants. Just a thought.
I remember the impact "Hiroshima" had on me as a kid. And the news, the drills, etc. Add to that Vietnam, the presumed "proxy war" supposedly between the evil Commies and us. Getting ready for school in the morning with the radio on and the news breaks with the daily "body counts." That was the daily routine for many years in my youth. The evening news, eat dinner while you see the latest reports from Vietnam. In my recollection, we saw more graphic stuff on TV and mainstream print media then than we do today. Buddhist monks immolating themselves in protest, napalmed villagers running for their lives. The troops slogging it out.
Perhaps it was just me and my imagination, but as a kid I sometimes doubted I'd see 30 before the PTB blew up our world.
Now the evil "Russkies" have their own problems and the (Red) Chinese own a good part of our national debt.
Now we got "terra." And perhaps that's supposed to be "The Bomb" of our time now. But so far just for myself I don't think it's quite the same as when gov'ts rattled their nuclear arsenals in the 50's/60's, nuclear testing went on in neighboring Nevada and we kids had duck & cover drills in school. And some folks built their very own bomb shelters (more impressive than duct tape and plastic wrap). And WW III was considered just a politcal mad fatal blunder or a technical "oopsie" away from happening. And I don't recall Pres Kennedy tellng us, "Go shopping."
But the various genies gov'ts developed such as nuclear & bio weapons are not entirely safely in the bottle. ("One Point Safe," "The Hot Zone," and "The Demon in the Freezer" are a few nonfiction books that could give you the willies.) When the Bushies spoke of not ruling out the use of tactical nukes in Iraq, it reawakened some of the old vibes. They would, it seemed, reduce the once "unthinkable" to the mundane.
We're supposed to be afraid of North Korea and Iran. And of course the "terraists." It doesn't seem quite the same to me though. Maybe just because I'm older and figure I'm lucky just to still be here at all. Right now I'm more afraid of what our own gov't might do.
As time goes on, perhaps indeed it is the Earth or the Cosmos itself that will give us a sluffing off.
At any rate, there's always something to be afraid of. 21st century technological capcities in the hands of minds not all that far removed from our first tool using ancestors is certainly one of them.
