what kind of sociopath would bomb a nuke plant? There are only 3 explanations:
(1) Putin is crazy. In which case he needs to be neutralized ASAP.
(2) Putin wants the world to think he is crazy and will stop at nothing to achieve his objective. Not as bad as 1, but somebody needs to lay down some red lines before he crosses more.
(3) Putin sees disabling the nuke plant as a strategic objective (cut power to enemy). Again we need some red lines. There are obviously many safer ways to achieve these objectives.
At this point Putin is entering the terrorist zone, and endangering millions who live outside the war zone.
There is a fourth explanation:
The nuclear plant is not operating....
