Why would Europe or the US actually want this war to stop? Since Putin took over in 2000 Russia had made some serious gains politically, economically… then Putin can’t help himself and attacks Ukraine, allowing NATO countries to conduct a proxy war. They finally have an avenue to weaken Russia, and it’s working. NATO countries really have no incentive to end this war (besides all the killing), and Putin is operating on pride while his country withers. This conflict may be happening until Putin dies.
