Berlin’s Pergamon has many artifacts, such as the facade of Qasr Mshatta (Jordan), for some reason. It’s infuriating to see this is still tolerated.
Should we return all such gifts? Why?
Should France claim back the statue of liberty?
The statue of liberty wasn't an archeological find to begin with.
How do you define "properly" given? I believe the ruler of the said country(be it a Sultan or a democratic elected gov) has all the authority to manage the cultural heritage of its country.
