The connection between Ukraine and Russia goes back to the baptism of Rus’ in 988, NOT to the anti-Orthodox mass-murderer Lenin!!!!

There is a large Ukrainian diaspora in Russia and the two peoples often intermarry. And millions of ethnic Ukrainians do speak Russian.
Those deep and close ties in the Slavic family will not be dissolved by the current protests.
