I think literally nobody knows the price either side is paying right now. And I do mean literally, including Trump, Putin, and Zelensky. The fog of war applies to participants, let alone outsiders who are basing our views on figures and claims that obviously going to be driven heavily by propaganda.

But beyond this, I don't think this war is about Ukraine anymore than a war in Taiwan will be about Taiwan. It's little more than a proxy for hegemony in both cases. Russia did not want NATO parked in their Achille's heel of the Ukrainian flatlands. NATO did, and we pushed forward against endless threats of it being a redline, essentially as a means of indirectly imposing our will on Russia and establishing a hierarchy of dominance.

And similarly, for those that don't the Taiwan-China history - the Mao led Chinese revolution was a success. The existing government of mainland China fled to Taiwan where they brutally oppressed the locals, in an era known as the 'white terror' [1], and established power through 40 years of martial law. And of course we backed them, solely to use them as a weapon against China, because geopolitics.

This is why these wars are so important for the participants. The US couldn't care less about Ukraine, but withdrawing without ruining our ability to militarily threaten other peer or near peer countries is difficult. And similarly the last thing Russia needs is more land, but if they never act on claims of red lines, then they can never expect their interests to be considered in the case of a conflict in interests between them and the West.
