Not so. 5 out of 6 are ethnic Ukrainians.
Roughly speaking, about four out of every six people in Ukraine are ethnic Ukrainian and speak the Ukrainian language. Another one in six is ethnic Russian and speaks Russian. The last one-in-six is ethnic Ukrainian but speaks Russian. This map shows where each of those three major groups tend to live. (about five percent of Ukrainians are minorities who don't fit in any of those three categories.)
- Viktor Yanukovych
- Viktor Yushchenko
Now that’s a confusing ballot.
If only 1/6 are ethnic Russians, how did Yanukovych win?
So the course of history comes down to having a deep water port, yet once again.

If Ukraine starts to break up
I am guessing Putin will move to annex it, as a warning
to the “westerners” in Ukraine that what they lose, or become detached from might be made permanent.
They voted in 1991 by 80% to have as much autonomy from the central Ukrainian government as is possible if independence isn't achievable(and would have preferred a return to the Czechoslovakia from which Stalin stole the territory in 1945). I personally know this area and just visited recently.
Given a choice between Russian language and Ukrainian language they much prefer Russian, but that has been officially suppressed since 1945 by the central government in Kiev. There is much propaganda that will deny the truth of this, but self-determination should be a two-way street.
