>Yeah but all that investigation in the "no immediate retaliation" scenario just delays the inevitable to some degree, right?
Nah, it actually matters quite a bit whether you get it right or not.
>If it turns out it WAS North Korea, they get glassed and I imagine China would be pretty pissed about that
In 100% seriousness, China wouldn't do shit to protect that norks at that point. If the USA could genuinely prove that NK had launched a nuke and hit cities, and gave that evidence to the world, nobody would stand in our way whatever the whining. National interest ultimately trumps all, and the Chinese would absolutely not accept mutual destruction for the likes of NK.
>not to mention the Russians who, in the film, have serious reservations about allowing missiles to pass through their airspace
Same as above, but even more so, and it's a total joke to even pretend they have the slightest say in a situation like that.
>And if it was a Russian SLBM that evaded detection, then, well, pic related
But the thing is that the US has decision making power in that scenario and that matters a lot. If we find out it really was the ziggers or chinese for some insane reason who did it, and we know our interceptors and shit failed, then we can blame the norks anyway and bide our time. Work hard on more interceptors, and position boomer boats with superfuse SLBMs and aim for a genuine first strike in a planned scenario aiming at actually winning a nuclear war by preventing them from getting enough of theirs off. Or a lot of other options.
But that's the point: to have options, not just 2 panic choices and you're not even sure who did it. It's worth it to be able to rationally decide and try to maximize your odds, get allies prepped and so on. One of the biggest scary bits about nuclear war is it can happen so fast out of the blue. But if you know you're going into one months ahead of time, you've got a lot of options.
