It's circus for the masses. It's a way to show how "important" he is (several helis), as well as legit and reasonable security measures.
I also don't believe in any war with the Baltic states, the west would never allow this, and RF would gain nothing.
My main concern about Russia is Russia itself, and their internal politics. If such huge nation doesn't progress, but continues its corrupt mafiesque system, you risk isolation in mind and economy. They already have massive braindrain, a few oligarchs own it all. It's all pretty sad for 140 million people + nations under their influence. I don't believe Putin is able to, or even want to begin transitioning to a modern state. Putin will not attack the Baltics, but if the country continues to deteriorate, perhaps an eventual successor will.
I'm not even saying Russia should or could be a normal democracy here, but you need a level of free press, you need people being accountable by their crimes, and you need a fair and functioning court system. (just couple of weeks ago, a Norwegian businessman was expelled from Russia labeled "spy" after running a successful cement business for years:

I think the siege mentality is very destructive, almost a psychosis on a national scale. Meant to distract people from the everyday failings of the system, while the oligarch elite sucks out as much blood and gold as they can from the country.
They talk about Russophobia, but I have seriously never met anyone critical of RF culture itself. They have great music/arts, great history, great jokes and are very warm and welcoming people.
