of course Putin's history lecture was biased. the part about Russia and Ukraine being one was true. the lie was that Ukraine was a part of Russia when really Russia was a part of Ukraine.
Kiev to Moscow is like Rome or Athens to London, Berlin and Paris.
Kiev was the cradle of civilization and Moscow came later ... in fact Russians were so butthurt about how "provincial" ( using the words from Anna Karenina ) Moscow was that they had to build St. Petersburg to get away from that shame.
St. Petersburg was supposed to be the European Capital that Kiev was.
I have been to St. Petersburg - it's fancy - but the weather is shit. Weather in Kiev 100 times better.
