Putin has no chill but you can kinda see why the Danes joining NATO would make Russia nervous. Sanctions are biting hard now and Putin must want to appear strong and unbothered, hence all his extra behavior lately.

A snippet:
To put it in simplest terms, Piontkovsky continues, Putin’s actions would be “revenge for the defeat of the USSR in the third (cold) world war just as the second world war was for Germany an attempt at revenge for defeat in the first.”
If the Russian speakers of Narva in Estonia were to conduct a referendum and Moscow sent in its forces overtly or covertly, how might NATO react? Piontkovsky asks. If NATO did not respond, “that would mean the end of NATO and the end of the US as a world power and the complete political dominance of Putin’s Russia not only in the area of the Russian World but in the entire European continent.”
But whether it would respond “is hardly obvious,” he suggests. Despite Article 5, many NATO countries would be reluctant to respond lest they trigger a nuclear war.
“Putin knows that they know that if they come to the assistance of Estonia, then Putin can respond with a very limited nuclear strike and destroy for example two European capitals. Not London and not Paris, of course.”

Well, that's just fine.
