I think the language talks are nothing but the pure political games. What does it mean 'to re-establish itself' or 'save the language' in that context? If you take the history a little further than 300 or so years, I'm pretty sure you'll find that each dialect of Ukrainian initially belonged to a group of people which physically prevailed another group. So, come to think of it, any language might actually be 'a language of an occupant' for the most people in the world. But after two generations the 'occupied' people would know the language of the 'occupant' and dump their native language. So, those who fight for the so-called 'their Ukrainian' with heat, would actually fight for the language of the 'occupant' of their ancestors. Their ancestors fought and died and the Ukrainian occupants killed them and wiped out their original language. Is that really something worth to hold onto despite the convenience?
