Hmm I'm not sure if museums can loan eachother items without the interference with the government. It could definitely be a possibility. But if I didn't completely misread your article it is describing an exhibition, not war trophies. I know several valuable treasuries were taken as bounty in earlier wars (talking about 18th century). I know I read something about several very valuable items being returned from Sweden, collected in the 18th century, to Denmark and Poland a few years back. But that was not a loan for an exhibition at all. This seems to be just that. After touring the world it will be returned to Iraq. I know I will go see it if it comes up here. OK so only the first sentence was on topic.
