As the war shows no end to it, I am thinking through these questions. Neither Ukraine or Russia are capable to win the war.
United States, and in particular CIA have already won this war and want it to continue. Russia and Ukraine are bleeding themselves, if not to death, then to a very bad economical, political, social, cultural, and moral state. The bleeding is continuous and there no visible end to it. Meanwhile Russia continues to sell oil, gas, wheat through the third parties and the economy of USA is not really affected; oil and gas markets are stable; USA may have gotten some economical benefits from this economical reshuffle, I do not know.
Corrupt oligarchies of Russia and Ukraine have won this war. As the corruption is rampant in Russia and Ukraine, a lot of war money may get into wrong hands during the war. Perhaps these people are interested in the permanent war as well.
Both Zelensky and Putin get some benefits from the war. Zelensky enjoys his international celebrity status. Putin becomes the only possible leader of Russia for many years to come.
Europe starts to realize perhaps that they are negatively affected (the flow of refugees, expense of joining NATO for Sweden and Finland, broken economical ties with Russia that have to be replaced). Direct neighbors of Ukraine (Poland, Hungary) are affected and I am expecting the relationship between them and Ukraine to worsen.
I am wondering where did the good will of Europe and United States go. They passively support Ukraine, to the level that it can not be overrun by Russia but not more than that. Perhaps it is clear that Ukraine cannot win in any case, without a major international military conflict in which the superpowers are not willing to be engaged in. This means a lengthy 'dirty' war in the middle of Europe, from which Europe does not benefit, but perhaps US does.
