President Putin has announced a partial mobilization in Russia

Which part isn't true?

There's an online corpus of the Russian language [0], whose entries of usage of the word Urkaine date back to the 17th century — you can easily see which preposition that word took throughout centuries. If you search through books on Russian grammar on Google Books, you will find examples specifically prescribing the preposition "на" throughout the 20th century.

The whole controversy about the preposition started somewhere around the year 2000, and quickly became political. For a disinterested Russian, who is not into politics, "на" would be a natural preposition to use with this word simply because he would have encountered it in classical literature, in the movies, or on TV. It was semantically charged only for those who were aware of the debate. The response from the linguists used to be that if Ukraine wants to use the preposition "в", it is free to do so for the Russian language spoken on its territory; but that it should have no say on how a language is used in another country.

I understand that in the recent years the usage of this preposition has become a political shibboleth; but I am not speaking about it from a political angle. My points are that the usage of this preposition, with this word, in Russian, is 1) historical, and 2) to those who aren't making a political statement, semantically neutral (i.e. it does not, in itself, connote derision, imperial ambitions, or anything of the kind). I have not made any claims about the Polish language (other than that, to my knowledge, it doesn't have articles).

The gist is, EU/UK no longer can work freely as they and their employers sees fit and government permission which is usually called work visa but can have different names is required. Some people qualify and obtain those, others don't qualify or don't bother. Usually comes with complications at retirement and long term life options and travel complications.

I'm confused why this has become a problem of speech precision. Even if the language is prices and people don't melt down, the reality on the ground often doesn't match the paper trail. Lots of people work without visa(arrive illegally?) or they arrive on one kind of visa but do stuff that require another kind of visa. Although these people work in UK/EU, it doesn't mean that they can work in the UK/EU.

The hate isn't on Russians as the carriers of Russian ethnicity. Such hate would be racist, i agree. The hate you see is on the carriers of Russian Nazism who openly espouses and propagandizes it. For example, many prominent targets of such a hate like those especially rabid Rashists propagandists on Russian TV are visibly not of Russian ethnicity. As another example - i'm a Russian and hasn't experienced any such hate even from Ukrainians i met here in teh last few months. I'm pretty sure though that if i were a Rashist and put the Russian Nazism Z-swastika on my car i'd become a target of such hate without people even bothering to check whether i'm of Russian, Jewish or Chinese ethnicity.

It is a trick that Russian propaganda actively using now - present legitimate hate against Russian Nazism as a racist hate against Russians. Don't fall for it :)

>Europeans have a cultural tendency to create moralistic almost religious justification for war and conquest. Whether it is the white man’s burden, or now denazification.

The main point of denazification isn't moralistic. It is a matter of survival. A nazism is "more" than just a fascism. The key foundation of nazist state is the "master-race/nation" ideology, and as a result one of the key characteristic of nazism is Lebensraum - "living space" for the "master-race/nation". While a plain fascist state, like Franco's Spain, can peacefully co-exist with its neighbors, it isn't an option in case of a nazist state like Germany back then or Russia today. Without denazification of Russia there is going to be no peace in the region, and with Russia being nuclear state it means that without denazification Russian presents a real nuclear threat to the world.

>The rest of the world has no reason to sympathise with actions that might trigger a nuclear war in Europe.

Of course nobody in the world is expected to sympathize with the Russian actions, and in particular with their intentional dragging of the world toward nuclear war. To avoid nuclear war Russia has to be stopped and the force is the only option for now.

> I used to think that European leaders understand that and it’s OK for Ukrainians to idly dream of wrecking great vengeance on Russia.

As far as i see, Ukrainians dream not about vengeance, they dream about Russia leaving them alone, something like having a kilometer high wall on the border with Russia. Unfortunately, without demilitarization, denuclearization and denazification of Russia the peace in the region isn't possible. In particular Russia wouldn't leave Ukrainians alone, and thus Ukrainians and the rest of the world have actually no choice wrt. what to do with Russia.
