So by that logic, the Turks should give Constantinople back to the Romans?
False equivalence, that’s an entirely different historical context. Things can apply to one situation and not another
Explain. How is it a false equivalent? Romans controlled the city / region for over a thousand years and were later conqured, and their land stolen, to use the vernacular of this thread.
You’re oversimplifying in order to compare the two. Wildly different historical contexts with entirely unrelated events. Distilling both down to “area conquered” just so you can make a point is reductive.
Beyond that though, why does it matter honestly? Does the fact that a city was conquered in the 1400s invalidate anything mentioned so far?
