Admittedly the situation in Ukraine is complicated. 

The country is historically important to Russia, but Ukraine is a country with its own language, culture and history beyond and preceding it being folded into the Soviet Union.

Both countries share a common heritage. Many in Ukraine have family in Russia and vice versa. 

Russia is a great country as are its people. I’ve been several times, including to the last World Cup in Moscow. I have friends on both sides.
