It's a really good question. I think many western people really can't understand what is the problem, and why people in the East Ukraine rebeled, and why Russians support them.
The key question here is the attitude to the WWII, and its heroes/antiheroes, and the 9th May (Victory Day). This is absolutely the key question. The treatment of veterans, the purpose to abolish the Victory Day, to make, officially, national heroes out of people like Bandera and others... and so on, and so on. You people in the west and especially in the USA have no idea how deep is that war in every Russian's blood. So yes, we ARE involved.
I am repeating, WWII is the key question.
