I was 15 in 1980 and I'm therefore old enough to remember the existential dread of nuclear destruction that was present during the Cold War - I'm in the UK, which would have been one of the hardest hit countries in any conflict.

What do I remember about that time? That most people completely ignored it - we escaped the effects of a global nuclear war through luck and sensible judgement by a large number of people on both sides who generally chose not to do something.

Unfortunately, choosing to do something is much harder (exhibit A: the UK's Brexit debacle) - so I'm genuinely worried about the potential for us to actually decide on what to do even if we all agree that something should be done.
