The only reason you still have a country is your nukes.
I have a feeling we are going to find out if any of them still work.
I have a feeling that the answer is mostly going to be 'no'.
Nuclear weapons are very difficult and complex devices. There are a lot more ways to not have them work than there are to make them work - if that weren't the case, the Manhattan Project would have taken a couple of weeks and cost a few thousand bucks.
These are not weapons that can be expected to work after years of neglect, and they contain components that can be profitably sold on the black market, so exposure to corruption is even more debilitating.
I would be quite surprised if as many as half of Russia's nuclear weapons were able to actually cause a nuclear explosion.
Sadly, half of a lot is still a lot. Even a hundredth, or a thousandth, of their nuclear arsenal could seriously fuck up your entire day.
