Essentially:
- nuclear deterrence includes Belarus;
- extended definition of weapons and use of weapons that can trigger nuclear response, such as massive air attack - think of the modus of Iranian strike against Israel - with aircraft, drones, hypersonic missiles, etc, or the use other conventional weapons if they create critical threat to the sovereignty of Rus/Belrus;
- nuclear weapons can be used against non-nuclear state which is supported by nuclear states (considered joint attack);

I dunno. Sounds like this new regulation is tailored to a specific ongoing conflict..., although considering new weapons (chiefly drones and hypersonic rockets) and their new type of usage warrants an updated policy.
