I agree with this take. Also Russia is not obligated to retaliate in the same way. They can respond asymmetrically by causing problems for Estonia in other ways and at a time of their choosing.

I think the people on the "pro-Russian" side who are always at the slightest provocation calling for some big escalation need to cool their jets, that kind of emotional response is just what the West wants.

They do these things because they aren't getting anywhere on the actual battlefield, in either the physical or the economic dimension. Psychological operations of little real consequence are all they have left.
