A lot of his research is accurate, and are things that I have heard previously. Something that is INACCURATE is the claim that the Sky-Father figure, z.B. Zeus or Jupiter, is a Middle Eastern construction. It is a falsity, and just one more way that Semitic researchers can shoehorn Europeans into caring about the M.E.

If you're interested in the origins of the Iranian, Vedic, and European conception of the Sky Father, this video is good.

Interesting that he mentions the 1964 KGB construct of palastinians as descended from philistines.....
