Not sure Australia-New Zealand make it? In fact, I'm fairly certain they would get hit. Just as certain as I am that North Korea would get hit.

I mean, just consider it from our (US) perspective. Any Russian naval assets that are harbored in, say, North Korea; I'm not sure that we could assume they don't mean us any harm. So I'm almost certain our subs launch strikes on North Korea despite them not really being involved directly in NATO-Russian hostilities. I think the same would go for US, (or NATO), bases and NATO naval assets harbored in Australia or New Zealand. There's just no way Russian sub captains let those targets go.

I think, in general, having had your nation destroyed is probably more reason for all those guys to fight each other and strike at targets of that nature. Not less.
