Number 51 – They filled their museums with stolen treasures

This is a pointless argument as EVERY museum the world over has artefacts in it's vaults that do not necessarily belong to them. Mr Grasse uses as an example the Parthenon marbles, well how about the Hope Diamond on display in the Smithsonian? This diamond was stolen from France, recut from the French Blue diamond which itself was cut from the Tavernier Blue diamond and was used in the French crown jewels, why then is it in America?
