Most Ukranians speak Russian due to eastern/southern parts larger than the western part. A lot of Ukranians speak "surjik" which is a mix between Russian and Ukranian and Western Ukranians speek a mix of Polish and Ukranian. I'd say there aren't many people that speak perfect Ukranian. Do you count people speaking "surjik" as Russian or Ukranian speakers?

There is no civil war, if it was a civil war the western part wouldn't survive a day. Nor the Russian speaking Ukranians want "Russian" Ukraine.
