Your reply suggests that you did not read the above post. Like I have said, the South East Ukraine actually has nothing to do with the historic "Ukraine". Before the creation of USSR, today's South East Ukraine was known as "New Russia" from 18th century on. Before 18th century, it was controlled by Tatars, not "Ukrainians" (the name Ukraine is a a Russian word meaning "borderland", and was adopted by a bunch of New Russian intellectuals in order retain a distinct identity from the rest of Russia). In 18th century, the South East Ukraine was an empty land that was settled mostly by Russians, so Russians were there before the word "Ukraine" or "Ukrainians" was even invented. Ask any Russian or European of that time WTF the word "Ukraine" means, and they'd stare at you confused. It was the 1920s communist government of USSR, which did a lot of weird stuff, that awarded this land (the New Russia) to the newly formed Ukraine SSR (soviet socialist republic). In the 1950s, Khruschev, an ethnic Ukrainian and effectively the ruler of USSR, also had Crimea transferred into Ukraine SSR allegedly for administrative purposes.
So like I said, I don't understand how one can possibly treat the Russians of Ukraine as some kind of a fifth column and a bunch of people do who don't belong there. Russians of the South East Ukraine came first to that place an long time before "Ukraine" even existed as a geographic or ethnic concept, and the ones who got displaced by Russians were not "the Ukrainians", and Tatars, the real victims of Russian expansionism of that time.
It's also utterly ridiculous of you to argue that ethnic cleansing, deportation, or racism is justified for the sake of a "stability". It's nearly like saying in the 1950s that African-American blacks should have been deported to Africa from the USA for the sake of "stability".
I could give you my version of stability recipee for Ukraine. Either, Ukraine defines itself as a bi-lingual and a bi-cultural country, giving equal recognition to Russian and Ukrainian cultures and languages, at least in the areas of the South East Ukraine, or perhaps Ukraine eventually splits into West Ukraine and East Ukraine, using the Dnepr River as the natural geographic boundary. At this point, the stability will prevail, and the comical and intolerant nationalists of the West Ukraine can transfer their capital to Lvov (which is where most of current Ukraine ruling elite come from) and start building the pure mono-ethnic country of their dreams, where everyone speaks and thinks in Ukrainian, and thinks that former nazi collaborator, guy known as Bandera (the fonder of UPA, the Jew and Pole exterminating organization so vile, that even Poland is disgusted at the attempts to glorify them), is the national icon and hero, while the East Ukraine Russians go back to their mother Russia. At this point everyone will be happy.
