Mr Rohl does NOT like the Aswan.
He is probably right.
The Aswan wiped out the Egyptian shrimp industry, but that may have recovered. The rising water table has led to the deterioration of most of the ancient monuments, and Hawass has been completing the destruction by the use of concrete “repairs” that are there for the short term benefit of Egyptian tourism.
Rohl does NOT like President Trump, and his work has always been derivative, so I don’t have much use for him at this point. He’s right on the money about the high dam though.
