The Russian economy seems amazingly resilient. Even this story, which tries to show Russia is hard pressed, shows their economy is growing this year?!
The article describes the economy as "not great". Which is a weird statement, because "not great" could be said about the rest of the world too, which has also suffered from high inflation interest rates and reduced production. I don't see anything in this article that shows it's worse in Russia than the parts of EU, that are also hit hard by the effects of this war.
But behind the numbers, I guess war stimulates economic growth, because the state uses a lot of money on the wart. And a significant share of the economy is actually waste on the war effort, that has no benefit for the population or society or long term improvements.
But let's do whatever we can to make it as difficult as possible for Russia. At some point their war effort will collapse due to the stress on their society, both economical and political.
And at the same time do what we can to help Ukraine win the war, and make their country whole again.
