I agree that electoral tactics are futile, and i personally have some major issues with Cornel West and some of the things he has said about communists and communism, but the fact remains that the Democratic party is the biggest obstacle to revolutionary organizing and revolutionary consciousness in the US. I can see an argument for supporting a spoiler candidate that draws away votes from them, especially when that candidate comes with a platform that has at least some semblance of anti-war messaging because that is something woefully absent from public discourse in the US and any voice on this issue with a platform such as that provided by participation in electoral politics is invaluable for shifting the public consciousness no matter what other faults those who popularize anti-war and anti-imperialist sentiments may have.
As Lenin said, the point of participating in bourgeois electoralism is not the delusional belief that you will be able to actually change anything substantial through the mechanisms of liberal democracy but the platform that this gives you to agitate and to spread your messaging.
From my point of view as an outsider looking at the situation in US politics my primary hope is that someone, regardless from which political direction, will make US interventionism unpopular enough for the US to stop meddling around the world. Ideally NATO would be allowed to collapse, funding for programs like the NED to be cut and US military bases and military aid to allied government across the world to be deemed unaffordable and be rolled back.
Of course I am realistic and I know that this is a long shot, US interventionism and empire is very much in the interests of its capitalist elite, so this will only happen if there is sufficient decline and turmoil in the US itself that its ruling class is forced to focus its attention inward.
Not zero, that would be absurd, but much less than Ukraine. There is a very simple rule of thumb for estimating casualty ratios in such conflicts, and that is they are directly proportional to the artillery overmatch since most casualties in conventional modern conflicts are inflicted by artillery fire. Ukraine has been stockpiling their best equipment and munitions which they received from the West for this offensive, and as a result they are managing to shoot a fair number of shells and missiles in order to try and soften up the Russian lines, but Russia still has an overwhelming advantage. In addition Russia also has almost uncontested air dominance at the moment which further skews the ratio in their favor.
