These nominal Jews are Erev Rav - physical descendants/embodiments/reincarnations of the "Mixed Multitude" - who are playing out, consciously or unconscioulsy their role in Divine history by trying to separate Yisrael from Eretz Yisrael, and to try and separate Moshe Rabbeinu from the two Moshiachs. As the Geulah gets closer, they will become more frantic, desperate and dangerous. Their ilk includes those like Pipi, Barenboim, Peres, Rahm, Rabin, Soros, Miliband, Machover etc etc i.e. most nominally Jewish leaders of today.
