To the west of the line, in #taiwan, territory cannot be acquired by #china (14th century) conquest (or communist revolution) but can be acquired by KMT conquest including massacre of tens of thousands of natives. No problemo!
Certainly no need to revert anything to an antebellum status quo like to the east of the line. Time to move forward and just call an election.
If we apply the same rules in eastern #ukraine? The conquest is old news, what matters is democracy for Donbas, right?
