I am not so optimistic. 80 years is one life-span. It feels absurdly short and quite possibly attributable to luck.

If the odds are one in a hundred per year, then that's awful. We traded periodic bad wars for a nearly inevitable catastrophic war, and people talking about how they haven't been used in warfare since that one time are akin to people talking about how well everything is going while sailing through the air after jumping off a cliff. So far so good!
I don't know what the right number is, but from what I know about how nuclear weapons are managed and what has happened in the past, I bet it's a lot closer to one in a hundred.
