I think anyone who has any engineering experience would suspect that never testing something will eventually result in it not functioning.
The reality of our situation if that we will keep fighting each other, that's a given. Best to test our nukes to make sure they work. Nukes that won't work can't save lives.
I know anyone alive today, not suffering from a mental illness, that would accept their leaders starting a global nuclear war.
Mind you, that's not a majority of the actual population given how low voter turnout is, but that's enough to be really scary.
