Ukraine

The 575k number is dead and wounded though, many of those will heal fine,

Much like soldiers did after WWI, right?

The reality is that many people have lost limbs, eyes, hearing, and so on. That means that many of these people are not going to end up being productive workers once they're released from service; they're going to be less-capable than their abled-bodied counterparts, and in a functional country, would end up being a drain on the coffers due to disability pensions (I strongly doubt that Russia is going to give the wounded conscripts any kind of disability payments).

Any way you slice it, Russia is destroying their own future. This kind of war, in a time where people aren't having children even at replacement level, simply isn't sustainable.
