I live in germany and as far as I know, there were plans to nuke us around '45. And one of the proposed targets was not really far from where I live. Thankfully it didnt happen, but this reminds me that no, I am not "somewhere else".
Of course at that time they had their reasons and its unlikely that it happens nowadays. But if some country not worrying about middle- and longterm effects gets access to nuclear weapons that is a risk.
OTOH, theres this "we have it, why should they not be allowed to have it too?" argument.
As for New Zealand, yeah, you are probably nice and safe there. For now.
