Attack in what manner? As you said Putin does not have military strength. The threat is already there and it is not being dealt with. Seems you like submission so long as it is small doses to non-Nato countries. Will you accept it if Putin nibbles off part of Finland? They are not NATO.
Tell me When NATO actually moves to prevent a Russian move that is likely to happen. Attack Munich, really?
If I were guessing I would think they would begin by destroying or electrical grid, since we seem to have no inclination to protect it.
I lived before rural electrification was introduced so I know how to survive with out electricity but 90 to 95 percent of our population would not survive, the collapse of electrification.
