Waltz all you wish. My point is, those works were not made by the Turks, the British museum or Lord Elgin. So,
Who were they made by? Chinese?, Germans?

Look, there is a valid argument to be made on both sides. And, it all boils down to opinions.
I see both sides clearly. The museum has a legal claim to them and Greece has a moral claim. In this day and age, who is going to win?
