Well, in theory that sounds great. But in the real world it's impossible. If Ukraine were a spherical horse in the interstellar space and could have flown away to some remote planet of its own, everyone would be happy to let them seek their own sovereignty or whatever they like to seek. In the real world every country pokes its nose in every other country's business. US pokes its nose into Ukraine's and Russia's affairs, EU pokes its nose into Ukraine's and Russia's affairs. Why shouldn't Russia do the same?
And what most simple Russians feel is irritation, spite, fear of war and terrorism and anticipation of worsening of already not easy economic situation which of course if happens will be accredited to the ridiculous inability of Ukrainians to maintain elementary order in their own country. Now for most Russians Ukraine is a notorious dog on the hay which worsens its own life and bring their neighbors down. Nobody wins. The world becomes a worse place to live, thanks to our "brotherly nation".What I see now is apathy, depression and fear of Russian invasion and war.
