No my take is there's a long line of people who have claimed to be the true Jews or followers of the "faith". The Catholic Church and replacement theology about 200 years ago, Muslims, Arabs, Mormons, Rastafarians, and blacks etc. etc.. It's never fucking ending.
The only "true Jews" are the same people and tribe that are practicing the religion, praying from the same holy book, celebrating the same culture and traditions, and speaking the same language as thousands of years ago.

Max Dimont
A compelling and readable account of the four thousand year history of a people that spans the globe and transcends the ages. From the ancient and simple faith of a small tribe to a global religion with adherents in every nation, the path of the Jews is traced through countless expulsions and migrations, the great tragedy of the Holocaust, and the joy of founding a homeland in Israel. Putting the struggle of a persecuted people into perspective, Max Dimont asks whether the tragic sufferings of the Jews have actually been the key to their survival, as other nations and races vanished into obscurity. Here is a book for Jews and non-Jews to enjoy, evoking a proud heritage while offering a hopeful vision of the future.
