I can give an answer, but it will be at least a few pages ...
1) but this is not a problem, the problem is that I will not be able to accurately and correctly translate into English ... the problem is not only in knowledge of languages, the problem is in semantics and meanings ..., even here in Ukraine and the Russian Federation, many are confused (because semantics and meanings of the same word are different! )
2) history + religion + stolen history and assigned name

3) we have had democracy for a long time, but in the Russian Federation there is an authoritarian system, and there has never been a democracy. The Russian Federation cannot be allowed to have neighbors living better than in the Russian Federation.
4) wealth of subsoil resources and human resources, and many technologies that the Russian Federation does not own, but Ukraine does not allow the Russian Federation to close the full production cycle without Ukraine and the Western world.
have questions, ask more specifically and I will answer .. even with examples if necessary.
