}Are you a British Israelist?
No, but what if I was? Just what is your hang up anyway?
The most elementary reading of Biblical history shows that Jews did not descend from the 10 Tribes of Israel which made up the so called Northern Kingdom. (They descended from the so called Southern Kingdom.) There is also no Biblical or other history to suggest those tribes either stayed there or assimilated with the Assyrians, as popular history (A division of Popular Mechanics) and uninformed Biblical fiction suggests.
Now tell us, just WHAT IS your agenda?
