Why does it matter if the Russian people know that? It’s not like they can will more tanks into existence, or just imagine foreign trade and get tangible goods as a result.

Russia’s actual real physical power has been broken by this war. Their demographic future is doomed. Their economy is in ruins. It doesn’t matter if the Russian people are happy with that, they can paint big “Z” marks on their wretched hovels in patriotic ecstasy and it won’t have any actual impact on anything.

It’d be ideal if Ukraine could have an outright victory and end the war fast, but failing that all that’s necessary is for Ukraine to survive and it can wait out Russia’s collapse.
