Probably not. Nuclear deterrent is just that, a deterrent. Once it's used, it's done. I don't think either side would use it on a "that's not fair" play - they'd really be reserved to respond/prevent/equalise some event/situation that would cause them to lose a war.

China killing millions of Americans as they cook in their batteries is different to a nuclear bomb or a biological weapon?

Hell it’s more attributable.
