No, but with a caveat.
The British Museum should merge with the national museum of any country that wants to raise an issue about "getting stuff back", with the ultimate aim of establishing an international museum organization solely dedicated to the preservation and exhibition of historical and cultural artifacts. In that way these things would not be returned but they would be shared amongst all the member museums.
Hopefully this would lead to museums of the same kind as the British Museum - free to enter for all, with objects presented in a fair context (rather than associated with modern nationalistic sensibilities that would have seemed ludicrous to those who created them) and where we can be reminded that we live on a world where so much we think of as "ours" owes its being to influences from many other cultures - popping up across the world.
