In “Truths and Counter-Truths: The Front of Information and Misinformation,” Fourth International (Trotskyist) activist Murray Smith provides a detailed analysis of the Ukraine-Russia conflict from a left-wing perspective.
Smith is a Scottish socialist who has been active in leftist politics in various European countries since the 1960s. Since 2009 he has lived in Luxemburg, where is a leader of the party “The Left” (déi Lénk), its leadership representative in the Party of the European Left, and associated with the European United Left-Nordic Green Left.
The article is thoroughly referenced and includes a very good summary of the Russian misinformation campaign. I highly recommend it. It can be read here.
