Russia isn't at war with Ukraine, it's a special military operation. Declaring a little exclusion zone outside all their ports for live-fire naval exercises isn't an act of war either. It'll be temporary, they'll be over by 2028, honest.

RU's permenant representative notified UN on day of "special military operation" that actions were in accordance with art51 (UN Doc. S/2022/154), i.e. regardless of however media is labelling war at propaganda level, RU specificly using art51 for justification.
