The diaspora is a very self-filtered subset though. Say, the Russian diaspora overwhelmingly opposes the Russia's aggression in Ukraine, while the population within Russia is mostly indifferent enough, and often supports it. (Note that all the Russian troops in Ukraine are not taken by military draft, but went to war voluntarily, for a generous fee, or in exchange for release from prison.)
Did they release the conscripts from 2023? Or are you assuming they've all died by now?
It's true that new soldiers are not conscripts, but I'd assume there's still some survivors from the earlier mobilisation and as far as I know once you're in, you're in, until death, incapacity or the war ending.
