Discussions, post-mortems, analysis, inflated egos, and all that jazz.

Petya, let’s hypothetically assume that it makes sense to communicate with you. Answer a couple of questions.

1. If the majority of the population of a territory directly states that it wants to secede from a state, is the opinion of the majority legitimate and should it be implemented?
2. Do you acknowledge that the majority of the population of Crimea voted in a referendum to secede from Ukraine and join Russia?

In other words, do you acknowledge the democratic principles of self-determination of a society?

I read one text, clicked "quote," and started writing, and now I'm looking at a different text. In other words, you're just talking nonsense. Now, when I reply, it will be the third one.)

In the case of Crimea, the situation you describe did not exist; many things were decided by the "little green men," cellulite-ridden women, and other fanatical Soviets. But the critical factor was the surrender of the local elites; without this, they would have quickly forced all the "Sharikovs" into a kennel.
It is also necessary to take into account the factor of the local population being stirred up by propaganda and myths about a better life, some kind of spirit, and "traditional values," as well as the deliberate resettlement of Crimea by Russians for many decades, which continues to this day.
That is, it was well done from both above and below.

In general, one should look at the legislation of the country to which this territory belongs. And only from this point of view should one reason about legitimacy. Let's say, hypothetically, I think that Kaliningrad would not vote for the Russian Federation, Karelia may dream of Finland, the Kuril Islands dream of Japan, Lviv dreams of Poland, etc., but who will let them. I call all this wishful thinking, which is either implemented legally or not.

Democracy is a term that is used when it is convenient, and not where it actually exists.

P.S. - regarding the majority, there is no reliable or relevant information on this subject, and we will probably never know the truth about Crimea.
If you need short answers, then 1. Yes, I suppose. 2. No, I do not acknowledge it.
The procedures for secession take years of preparation and deliberation, not 2 weeks of chaos.
