Russia couldn't fight NATO, particularly after (a) losing so much in Ukraine and (b) telegraphing how they fight. They would have 1,000:1 loss ratios. They'd have to resort to nukes or biological weapons.

Define “fight”. I believe you are limiting your thoughts to kinetic fighting. 

Consider cyber, economic, or political fighting. 

Btw. Naval resources when at sea are probably invulnerable to the kind of surprise drone attack that seems hard to prevent.
