Then I went to Kiyv and and asked someone for directions in broken Russian. He said, "Why are you speaking Russian? We're in Ukraine, you can speak English for example". At this point I realized in the West of Ukraine there were already some tensions regarding the coexistence of these two groups.
I experienced a lot of good things both from Russians and Ukrainians and it breaks my heart to see how Putin is sending these poor guys from conscription and sends them as fodder meat. I hope there is at least one sane person around Putin and they do what others had been trying to do in such a situation[0] - but this time successfully.

It has close industrial, commercial and cultural ties to Russia.
In a reverse scenario I could well see Lviv revolting.
