There is a Russian saying.... "Where there is the Russian language, there is Russia". It has long been part of there strategy to claim foreign lands as there own if Russian is spoken by a part of the population. It is why they basically banned all other languages during Soviet times. They understand how useful it has been for them in erasing the identity of sovereign states by implementing these measures.

Russia is an Empire of Evil and Murder, 800 years of their history should prove that. Every country in Europe should take note, especially the Baltics where their territorial boundaries have been seeded for the last 100 years with Russian speakers who refuse to adopt the countries spoken language (ex: Estonia).

Ukraine needs to eradicate the Russian language from all it's territories as a strategy to strengthen their sovereignty and culture.
