As far as I know, this video has not been posted here before. If it has, I apologize for reposting it. I found it on the website of Izquierda Socialista, the Argentine section of the IWU (FI) [International Workers Unity- Fourth International).  It is in Ukrainian with subtitles in English. It is a particularly compelling and clear answer to Western and Latin American left apologists for Putin's imperialist aggression by Sergey Movchan.
