To be explicit for y'all:
People I don't worry about when they talk about nuclear forces: Medvedev, Prigozhin, Kadyrov; any R or US TV host; anyone in Congress or the Duma; anyone online; anyone in a non-nuclear country, including Zelensky, Lukashenko, Scholz, etc.
People I would start hoarding iodine pills if they started holding urgent press conferences about nuclear forces*: (T-1) Putin, Biden, (T-2) Patrushev, Sullivan, Gerasimov, Austin
(*to be clear, we're not *remotely* close to that)
So putting my guessing hat on; it'll cover:
* Radiation/nuclear safety
* Indefinite extension of Grain Deal
* Price restrictions on Russian energy
* Release of prisoners and deportees -- POWs; forcible deportees; children
* Restoration of Ukrainian territorial integrity
* Withdrawal of Russian forces
* Reparations for damages to be paid by Russia
* Funding and technology to restore damaged infrastructure and offset environmental damage
* Effective security guarantees (the Kyiv Security Compact)
