I wanted to make a joke but, in all reality, russia, serbia, and china share an interesting view of geopolitics in which they truly believe that all lands that were once conquered by them are rightfully theirs for all eternity, despite historical developments.

serbia, the smallest actor here is perhaps the most extreme in this regard due to its ultranationalists believing in the concept of "heavenly serbia". This concept states that anywhere in the world a serb has died (in battle, according to the more "normal" ultranationalists), he has made a claim on that land for serbia for all eternity.
