> Ultimately, we have made it

Spinning the present situation or the history of nuclear arms as a high-five, "go team human!" success story is... quite the take (Vasili Arkhipov, Cuban missile crisis generally, the current doomsday clock being "the closest the Clock has ever been to midnight in its history").

> You don't have help. But perhaps you could at least avoid discouraging people unnecessarily?

More germanely, you don't have to worry yourself, but at least avoid discouraging people with legitimate worries who want to take precautions. Even the present situation with nuclear weapons, precarious as it is, would likely be more precarious were it not for the political pressure of the people worrying in the 1950s and 1960s and up to today.
