The jews didn't start we wuzzing as Israelites until relatively recently
British Israelism is way older than Ashkenazi Israelism. In fact king James (The dude who commissioned the king James bible) was an advocate of Anglo and Norse Israelism.
> M. le Loyer's The Ten Lost Tribes, published in 1590, provided one of the earliest expressions of the belief that the Anglo-Saxon, Celtic, Scandinavian, Germanic, and associated peoples are the direct descendants of the Old Testament Israelites.[3][10]:176 Anglo-Israelism has also been attributed to Francis Drake and King James VI and I,[10] who believed he was the King of Israel.[3] https://en.m.wikipedia.org/wiki/British_Israelism
