Have you tried to ask the Ukrainians if they want to, there was Russia?
First of all "Ukrainians" are not a homogeneous ethnic group. The Western Ukrainians and the Eastern Ukrainians are as different as the Chinese and the Japanese. Right now, the Western Ukrainians are trying to impose their culture and language on the Eastern Ukrainians, and this is the trigger behind the ongoing civil war. Even if Russia stays away, unless the Western Ukrainians stop their ethnic harassment, the conflict will never end.
Do not tell tales!!! Are you from Russia? You here on the forum always defend the position of Russia. What you say is part of Putin's propaganda. You even ever been to Ukraine? In 2012 the whole of Europe saw that you're lying. There is no difference between the West and East of Ukraine.
