Sorry to say, but that's a false equivalence. No "provocation" justifies invading a country and starting a hot war.
And this is coming from someone who believes that Russian-majority areas and Crimea should just be integrated into Russia.
Because I don't believe in the "principle of territoriality and the inviolability of borders" as far as internal segregationist movements are concerned (that's the doctrine that justified Kosovo's independence).
Putin is a war criminal and a piece of shit dictator, and those facts are not diminished by anybody else being the same.
