Is there a particular reason this announcement was made today? Just seems like such an unusual announcement. Didn't realize I needed the 5 UNSC countries to calm my anxieties about nuclear apocalypse today.
NPT's conference take place every 5 years, and it's supposed to take place in New York April 2020, but will have to be postponed again this year due to COVID. I guess they making this announcement to avoid possible worries of the world.
The point of total nuclear war is not to declare a victor anyways. States that can ensure MAD have a nuclear deterrence based on irrationality, of which you cannot exactly reason rationally like this.
FWIW. if your city has blast doors at 100m+ depth you are for sure joining the nuclear exchange.
