None of that answers the question. What does NATO practically do as response?
Principles, doctrines, ideas aren’t a response (or even an active decision to not respond)

Yes im asking what that response would be.
Say Russia lobs some ordnance at Poland. Kills a kid. Claims it was an accident and definitely totally won’t happen again.
What in your mind does a response look like? Find a Russian kid? March on Moscow? Nukes? Air strike? Angry letter?
Obviously it’s a test and there is a need to push back but how is the tricky bit. Anything you do would be an overtly action against grey zone deniable action.
