He has a point. Those who doubt can look at how ancient sites are treated not just in Egypt, but in Muzzie countries the world over.
Don’t return them to Egypt. Muslims have absolutely no appreciation other than disdain for anything of antiquity.
And I wonder what happened to the “lawyer” who was trying to sue Israel for the return of goods an gold “stolen” in the Exodus, which could certainly be construed as an admission that it happened. Is he still amongst the living?
