What to do with the returnees?

But they can come back Pannonian, you are not legally allowed to take of citizenship if someone will remain stateless.

In the USSR it was just the case. Some dissidents (for instance, Solzhenitsyn, Rostropovich) had their Soviet citizenship taken away and were deported from the country. After that they received another state's citizenship, but for some time they had none.

“It is so inspiring! Especially from the one who more than once claimed that, in fact, NATO armies (including the French one) were doing anything but defending freedom or democracy.” Who? If you claim that it is my position, you surely had problem in reading text (or understanding).

I don't have problems with understanding/reading texts, perhaps I can't always detect irony and sarcasm. In live communication one can figure this out by intonation and facial expression of the interlocutor. Since in your post I had neither (and you didn't give any other clue) it is quite understandable that I could misinterpret the message. If you aim at clear understanding, make sure others get your intention.
Yet if it was sarcasm, it doesn't reflect great credit upon you. For a significant part of your life you have been doing what you despise. Talk of hypocrisy.

“Do you blame cars in accidents?” You should more about Car’s company blamed for accidents due to a default. So, yes, when a car is involved in an accident, we can blame the car. Then, do you deny the car was part of the problem, or you just pretend that it nothing to do with the car, as the killer had been on foot, it would have been the same result?

“And if a person killed someone with a knife, must we blame the knife since it definitely has some relation to the murder?” Who spoke of blaming game, excepted you? Yes, if I kill someone with a knife, and if this knife was designed to kill, yes, the knife is part of it: without the knife I can’t stab someone. I may strangle him/her, but I can’t stab. So, what is the part you still don’t understand?

You know perfectly well that there are accidents in which cars functioned alright and knives meant for killing are not always the ones used in murders, yet you go on being childish in blaming objects for what humans do. The same as kids hitting some tool or thing which through mishandling hurt the owner. So keep kicking the rake that struck you after you stepped on it and shout "Bad rake!"

“The USSR almost banned religion” Never, that is legend: From Wiki: “The main religions of pre-revolutionary Russia persisted throughout the entire Soviet period, but they were only tolerated within certain limits. Generally, this meant that believers were free to worship in private and in their respective religious buildings (churches, mosques, etc.), but public displays of religion outside of such designated areas were prohibited.”

Keep quoting wiki which tells me about the life in the USSR. I LIVED IN THE USSR AND I KNOW THE WAY IT WAS.
When I was baptized (at the age of five) I was told to keep it deep secret and not to breathe even my friends in the kindergarten a word about it. My godfather had to keep it secret as well because he was a Communist and the chief engineer at a building company. If you were spotted attending a church (even on a holiday such as Easter or Christmas) your boss - at the instigation of the communist party chapter of the enterprise you worked at - would severely reprimand you and your future career advancement was forfeit. Because of this very reason my godfather wasn't even present at the procedure of my baptism, so all the neccessary rituals were attended to by his wife (so, strictly speaking, his wife IS my godfather). Priests were supposed to report on the flock to KGB. So the Soviet freedom of faith you try to convince me in was true only for people after 60. If you had any aspirations in your life you could see the church only from the outside (and from a safe distance too).
