The #Arab League basically abandoned use of the #Khazar myth after 1948--tho cranks such as Saudi UN envoy & histrionic windbag Jamil Baroody periodically trotted it out.
Its recurrence is therefore cause for deep concern: 1) a sign of dangerous regression to zero-sum game: denying opponent's identity does not induce him to compromise 2) technique is same: historical distortion disingenuously citing scholarship from the opponent's community. Cheap trick.
