WWII Shipwreck With $200M In Silver

A British cargo ship laden with over $200 million in silver, which was sunk off the Irish coast in very deep water by a German U-boat during WWII, has now been located by treasure hunters.  As THIS 2 minute segment from the CBS News last night makes clear, it's only a matter of when, not if, the silver is salvaged.

But whenever there is discussion of salvaging parts of the Titanic, which is apparently in shallower water than this wreck, a hue and cry is raised about respect for the deceased.  But no such concern is mentioned about this wreck. Are 'war dead' less worthy of respect?  Or is $200 million of pure silver simply 'a different issue' than broken china and silverware?
