It’s a tactic of fear. Invoke fear in civilians and you can get them to do what you need them to do. If there are soldiers with weapons in front of a voting place who quite clearly belongs to a specific party without so much as openly stating it, then people are going to vote for that party out of fear. That is what I called selfpreservation. They don’t want to die.
If by any chance you wouldn’t be swayed by such blatant show of force then I admire you. The majority of people are swayed. Especially when there are literally truckloads of soldiers all about the coutryside. And as you said: voting with the more powerful state. At that moment the Russians had their force in Crimea and the people chose selfpreservation. Was it the right choice? For Ukraine? No. For Russia? Yes, of course. That’s why they showed force.

I don’t think they should invade those places, no.

Then why do you follow that logic with Crimea but not the baltics?

Having control of the northern black sea is obviously important.

Ah, now I understand. “We need a harbour that’s ice free the whole year around.” There are some holes in that logic:
a) Russia had/has a lease on the Sevastopol Navy Yard. That’s where the Black Sea Fleet was/is anchored. b) Russia has Novorossiysk, a harbour that is ice free all year around and is one of their biggest - if not the biggest - trade harbours. They even have a Navy Yard there.
So why do they need Crimea? To get their stuff from Rostov at Don all the way to the Dardanelles? They already could do that since they had the other half of the strait of Kertch.
And the other question: Why do they need the control of the northern black sea?

Russia is obviously not invading anywhere else in the foreseeable future, let’s move past that.

Why would you think that? Spokespersons of the Kremlin are rattling their sabres for Svalsbard and they are painting themselves as an oppressed minority. Does that sound familiar? Yes, since Crimea, Luhansk and Donetsk were the same.
Svalbard is protected by a treaty, but Ukraine also had a treaty with Russia about territorial integrity.
Abkhazia and South Ossetia are regions that were carved out of Georgia, an independent nation.
Transnistria is a region of Moldova, also an independent nation. Transnistria has requested the annexation into Russia. So the question is, do you recognize Transnistria as a sovereign state or is it a part of Moldova? If it is a part of Moldova it would be an invasion of Russia. Although since they already have troops there it is an ongoing occupation.

Since Russia is still engaged in occupation and invasion and is still rattling their sabres, can we really move past the threat of invasion?
The thing is, we don’t know what they are planning. We don’t know what they are aiming for. But we see that there are tactics in play they use quite often. For instance the tactic of propping up people that want their own state (see Luhansk, Donetsk). Then going in to help them.
Then there is the tactic of subtle influencing. The problem with this is that there are just clues but no real evidence. So it is really difficult to prove that Russia is behind such things like the Brexit for instance. But there is meddling with the elections of the United States.

But so much text for just saying that Russia might as well already have started the Third World War and all machinations are going to culminate in it. Does Putin want to do that? I don’t know. I don’t think anyone knows except him and perhaps a handfull of his confidants. So we as ordinary people will never truly know. The parallels to Hitler and the Second World War are there, some tactics stayed the same (fear, forceful annexation), tactics changed (propping up partisan governments). It’s all a question of time, but I’m not confident enough to say that Russia won’t be annexing anything else or will stop once Luhansk, Crimea, and Donetzk are independent and can be integrated into Russia. There are too many clues to the contrary.
