The western politicians and the public acting surprised after ignoring all the warning signs all these years is truly amazing to watch.
Saying "look at the map, NATO surrounds Russia" is sort of akin to looking at a map of city lights on the earth and calling it a heat map of murders. Not the greatest analogy, but hopefully gets the point across.
The crucial difference, in case is not clear, is that a missile placed in Ukraine would hit Moscow, the capital of Russia, in minutes. This is much more threatening to core Russia interests and Putin would not live with it.
Before rushing to putting all the blame on Russia just because "Putin-bad": I would strongly encourage people who are interested to know more to watch the following talks, from ages ago, given at reputable US universities because let's be honest, none of us is geopolitical historian two weeks ago on this topic so why don't we all do a bit more research.

In Crimea and in some parts of Donbas the inhabitants identify as Russian.
So what? So could one from Latvia or Estonia. (Not to mention Leningrad.) So you're saying that justifies him invading and subjugating those countries too, aren't you?
The point is, these experts may understand geopolitics, but they don't understand people. These countries don't join NATO because the USA pushes them or because "NATO wants" to expand. They do it because they're afraid of an aggressive state with a history of offensive wars. They don't want to became Putin's vassals like Belarussians who recently tried to decide about themselves and met with violent terror. So yes, in the mind of Putin it's the fault of NATO, but it is a very sick point of view.
you are in misunderstanding why countries join the alliance
Of course smaller countries with less security guarantees want to join NATO! It's the most powerful military pact and once you are in you can go around punching up against much larger countries! Who wouldn't want to?
Even Russia wanted to join NATO, an idea floated after WWII when the Russians fought against the Nazis alongside the allied forces. Of course that was dismissed as a pipe-dream because the existence of NATO was to contain Russia to the east.

Ironically, you have just confirmed what Russia believes justifies its actions in Ukraine.
Nobody sane.
Gas is still a hot commodity in the world and Russia will sell it, anyway, and maybe still to Germany as they've announced they were restoring normal gas flow through Poland to Germany.
Now, the good general point that one would have hoped all countries understood by now is: Don't become too dependent on a single supplier for anything, especially energy.
