Ignore the idea of the script, it means nothing.
This is what it really means:
Every respectable monotheistic religion needs an adversary/satan and Akhenaten’s cult of Aten is no different. In ancient Egypt, this spirit of evil and destruction who dwelled in eternal darkness was known as, Apep. Apep commanded an army of demons that plagued mankind according to the ancient tradition. Apep later became known as Apophis, patron of evil and darkness; the serpent.
What Obama is wearing is a talisman ring dedicated to the serpent god Apep, patron of evil and darkness. It was given to him way before he got married and Michelle was okay with him using it as heir wedding ring.
I have researched this style and it is an antique variety either Saudi or Egyptian.
