One main difference between them is that the Jehovah's Witnesses speak and tell people that the name of god is Jehovah (or Yahweh).
The Jewish people practice not pronouncing the name of the Divine God because of superstition or that the divine name is too holy to be spoken by imperfect lips.
Another difference is that the Jewish people believe that Jesus is NOT the Messiah.
The Jehovah's witnesses believes otherwise.
Judiasm
catholics have the most but Judiasm is the fastest growing religion
Judiasm is the religion that is followed by the Jewish people. It is considered to be a monotheistic religion and originated in Israel sometimed during the 1st century.
Its Christianity but also Islam is a fast growing religion too. The three main religions are.......... 1st Christianity , 2nd Islam and 3rd Judiasm.
There is no "eastern religion" or "western religion." Christianity, Judiasm, and most the religions practiced in the Western Hemisphere originated in the Eastern Hemisphere and spread around the world. Islam, what is thought of as a very Eastern religion by most people who don't know much about it, actually spread up through Africa and into Spain by the Moors, who were eventually defeated. Religion has no bourdaries.
Radical Judiasm is like any other religious extremism. It is the belief that the Jewish religion is the only correct one.
Judaism is practiced by the majority of Israel's citizens. The Arab minority practices Islam. And the Christian minority practices Greek Orthodoxy, mostly, but other Christian sects are alive and well in Israel, also.
Roughly 75% of Israel's population is comprised of Jews. The question of "following" Judaism is an entirely separate issue.
