false narrative that the possession of these nuclear weapons is actually making us safer when they're not.
I suspect it trades one kind of problem for another. While the world has been on average more peaceful after WW2*, it's also possible that a war between superpowers could wipe out the majority of humans and animal life in something comparable to the Permian Extinction Event.
Even as an energy source, nuclear power has often presented a choice between small continuous problems (like carbon smog) versus headline-making events like 3 Mile Island and Chernobyl.
* History is war after war, peace was a fluke.
