Now what do you do if you detect SLBM launch from somewhere in the Pacific Ocean? Who do you nuke?
So the answer for deterrence purposes is you don't need to nuke anyone right away, immediate response is only one layer of the onion when it comes to nuclear deterrence.
This doctrine is called "launch on warning". It hasn't been official US policy for 20 years[1]: In 1997, the Clinton administration changed the official policy away from launch on warning to one of retaliation after withstanding an initial first strike.
So Russia is probably the best choice.
IIRC both have about 60 subs and Russia is back at their post-1991 strength.
See the recent WaPo article about them mapping undersea cables.
Yes, I am serious. https://en.m.wikipedia.org/wiki/Military_dolphin
Honest question - is this the function you'd be optimizing for? What are the implications of earlier space-based detection of a launch? Presumably fast detection of a launch plume would help you find and hunt down the sub, but at that point the missiles are already in the air. I would think that the more important factor is where to hide to minimize chance of detection prior to the launch.
A submarine is at least pretty stealthy, but the heat signature of a missile launch is impossible to hide.
Another way to look at it: the satellite systems described in the article (SBIRS and DSP) are optimised for early detection of a launch. So when considering the deficiencies of those systems, it's correct to consider a hypothetical adversary who optimises for the opposite.

In fact, I am worried about TacNukes - like the kind we see in James Bond movies - being smuggled INTO A CITY!

Here is an article about loose nukes.
North Korea has ALREADY given Syria nuclear material to build a functioning nuclear weapons facility. Google "operation orchard".
I am worried that, as soon as we attack its regime, some sleeper group would use nukes somewhere.
And what do we do in general with rogue nukes? How exactly are they accounted for across every country?
We sleep soundly because there exist men willing to do inhuman things to ensure our security. It's unpleasant until compared to the other options. That's what genuine heroism is like. When Putin is praising that organization he is thinking of something like this. We live very sheltered lives I think.
I was trying to explain to my wife the concept. The example that I used was the person who wants the retail store password. They don't call the store and say over the phone 'hey I am at the Global Mall Store and forgot my password can I have yours?'. Immediate red flag. They start with something simpler and build a reputation as legit. Something like 'hey I am at the Global Mall Store are they saying you have to work until 7pm on Christmas also?' [1]
[1] Then follow that up with other requests over weeks finally culminating the 'password' question.
Naturally in school we were rehearsing in case of a strike but very few fallout shelters existed so we improved our response time for getting in position safely underneath our desks.
I am seriously, completely confident that name would fool the person it's meant to.
At best, it’s trivia, at worst it provides advantage to a rogue nuclear power with active concentration camps.
