Ukraine

Yes, unironically.

If you think you should be allowed as a russian to live in a country russia is engaging in psyops, social destabilization, and some cases even open warfare against, you should be fucking forced to decide. Do you want to stay where you are and have been welcomed despite all your country's bullshit then do so and blame your relatives at home because they don't make it stop. Blame yourself as well because you dodged that bullet for a good life elsewhere.

All more logical and reasonable than to expect your host country to roll over and take it for your convenience, especially when most of the russians living elsewhere are just as indoctrinated as those at home and are often willing assets for the russian hybrid campaigns, espionage and sanction evasions. No victim nation of russian aggression can be faulted for trying to protect themselves from a new kind of warfare.

Russians that wholeheartedly condemn what their country is doing probably aren't travelling that often to russia, for fear of being arrested. Thus, the ones regularly crossing the border are likely the ones that either support russia, or are suspiciously silent. Obviously, these are people we don't really want in the country anyway, because they're terrible people. That's before we bring in the security aspect of allowing russians that are supportive of a potential invasion of the country to stay in the country. Those people are a sabotage and intelligence risk.

Any russian that doesn't explicitly oppose the current russian regime is complicit. Even more so if they live in a country with free speech. There are plenty of videos online where you can see the preferred methods of dealing with russians engaged in invasions - why not extend the treatment to those supporting them?

Yes, actually. Believe it or not, every Russian and Ukrainian had to make that choice already, and WITHOUT the 1 in 3 months visit option. This is a pretty small problem by comparison. Also, nitpick, but doesn't a couple eventually move into one place anyway?

Plenty of Russians are still not opposed to the war with Ukraine. I suppose we're at a standstill, then.

As for pros of doing so, the article says it, potential sabotage. We already have had troubles at the Poland/Belarus border for years, so this seems fair to me. Could also be specifically preventing Russians working in Lithuania and then heading back to take advantage of/boosting Russian economy.

They have fascists and a fascist-lite party.
Fuck that country
