It's been surreal to see the consensus opinion on this issues here in the west. As the old saying goes, the first casualty in war is the truth. I don't pretend to know what's going on from my vantage point, but I'm struck by the simplistic, moralistic, and confident view that I constantly hear from western sources.
Personally, I think this war has been very costly for Russia. Wars usually are, but that this has been extremely costly for Ukraine, orders of magnitude worse. Further, as bad as the economic sanctions are for Russia, the boomeranging economic harm of the sanctions on Europe will probably have severe consequences with unpredictable political repercussions. Further, I think western sources misunderstand Russian motives and goals and have an incomplete understanding of who is doing the actual fighting in Ukraine. Both sides of the war in Ukraine are largely fought by Ukrainian citizens (i.e., the "Russians" in the east are mostly Ukrainian separatists, to some extent Russia is fighting the war by proxy too).
Unmistakably, this is a massive tragedy for Ukrainians and I think it was avoidable. I wish we were more introspective about what role the west has played in this conflict and continues to play to minimize future catastrophes and hopefully bring this to a resolution more quickly. I don't and can't know who is "winning," but I'm pretty sure we're all losers in this conflict. In the end, Russia will probably control the regions of the DPR and LPR and its primary trading partners (particularly for energy) will be the east. China and India long term are probably the only winners--they will get subsidized energy and be economically more competitive compared to European industry. The American goal of weakening and isolating Russia may ultimately be a success; I don't think it will have been worth it. I sure wish the Minsk accords had just been followed and this all could have been avoided.
