Judaism will "smash" Christianity and Islam and all the rest because that's what Judaism "believes". It's more than a mere coincidence this book - published shortly after 9/11 - reflects the agenda of open borders migration and church fires we see today. -- Does Rushkoff's Judaism intend Israel to be the sole nation state...or will that also be abolished to the greater good of a borderless NWO ?
Rushkoff forgets that Jews are also required to BELIEVE in a Messiah. Belief in the eventual coming of the MASHIAC (Massiah) is a basic and fundamental part of traditional Judaism. It is part of Rambam's 13 Principles of Faith, the minimum requirements of Jewish belief.
