Here are some recent pieces, from a variety of political perspectives, helpful for understanding the geopolitical implications of the Russia-Ukraine (and effectively Russia-U.S.) conflict.
Most of these focus on the recent Russia-China gas deal, and together they underscore the importance of the Russia-China relationship in the unfolding multi-polar geopolitics of the post-2008 world economy.
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.
In “A Popular Front for Russian Nationalism,” Dale Street of the British socialist Workers Liberty web site provides a thorough analysis (and deconstruction) of the so-called Yalta Declaration. It includes a detailed assessment of who the Ukrainians, Russians, and westerners were who attended the Crimean conference that resulted in this (one-sided) statement.
