Not the type of "conventional warfare" that's common today, but I thought a lot about total nuclear annihilation as East German teenager in the middle to late 80's. And if war had happened around that time, it probably wouldn't be the cliche of Soviet tanks flooding the Fulda Gap, but instead Germany would have been a nuclear wasteland within half an hour of the start of the war. Movies like "The Day After" (US 1983) and "Briefe eines Toten" (SU 1986, don't know the official Russian or English title) didn't exactly help to settle the overwhelming anxiety ;)
Yes, definitely. My proper awareness of these things doesn't really start before the 1990s, a golden age in terms of European expectations for peace, I guess.
