I grew up in the U.S. in the 80s. I remember my dad telling me that it would be very easy for us or the USSR to destroy each other - all they would have to do is press a button and missiles would fly over and blow up the country. For some reason I imagined that in both countries' main government offices, there was a big gray box with nothing on it but a red button for this purpose.
