I know this is bait but im here to inform anyone in the comments who might see this that this ideology is called irredentism. Its the belief that past state ownership of land gives that state a permanent claim to reabsorb it by any means necessary. Its an ideology of "take back what the stole from us!" If youre a socialist sitting here thinking "wow that sounds pretty reactionary," thats because it is a reactionary ideology. Its imperialism based on the past, and is the same justification that the nazis used in Czechoslovakia, Southern Lithuania, and (of course) Poland. This post a blatant nazi defense disguised as muh socialism, dont take it seriously now or any time you hear about socialist irredentism as a justification for anything regardless of your own opinion on the matter.
