We can go all the way back to Gorbachev and we won’t find a single root cause of this present situation, but instead many different factors. But I see no reason to assume that the Russian SMO on the DPR and LPR is the sole, deterministic cause of this labour conscription, disregarding all agency of the Ukrainian government and NATO on their own internal policy matters. Japan might’ve started the war against the USA in WW2, but I don’t think it removes the agency of the USA government from putting their Japanese-Yankee citizens in internment camps or nuking Japan twice.
What the other comment seems to imply is that all the issues there are caused solely by Russia’s participation in the Donbas War, disregarding how the article goes in detail about how those things listed (such as the labour draft) are policies made by the Ukrainian government. It is clear as day that the Ukrainian government values retaking the east and privatising its property much more than the lives of the citizens they claim to protect.
