Art theft is a real issue in the US and Europe. If an art thief stole then sold a painting owned by an American to someone in China, would you support seeing the stolen property returned to the original owner? Would you take seriously the idea that the owner wasn't entitled to have their stolen property returned since there was a non-trivial chance the art could be stolen again?
It is a much different scenario if an artifact is destroyed either intentionally or unintentionally.
I'm not at all comfortable with the idea that Americans shouldn't return stolen antiquities because America might destabilize the region of the original owner again so badly it could be destroyed.
I'd forgotten to respond to this earlier but it's been bugging me, so I'd like to note that a significant amount stolen art is never recovered. In some cases prominent and expensive artworks have been destroyed by the thieves when they couldn't move the art in an attempt to destroy the evidence. Stolen art is sometimes destroyed either intentionally or unintentionally.
I'm sure the citizens of Philly wouldn't be susceptible to any arguments that Baghdad would be a better place to store the Liberty Bell.
