some additional thoughts, I am not well versed enough in the Hobby Lobby story to have a good opinion on it.
What is not stolen today can be considered stolen tomorrow with changes in governments on either side. Then there are those lost to conquest.
There were recent stories about Ethiopia demanding back items lost in war [1]. The concerns must be, are they better back where they came from and are they even owned by who is now in power? the other concern is how are they protected by changes in who controls a region? We already witnessed what groups like ISIS are willing to do.
so my real questions are.
How recent must a change in possession occur for it to have relevance on who owns something? Does the means of how possession was done account for anything?
