Don't Mess With The Jewish Navy !
The Jews, also known as the Jewish people, are a nation and an ethnoreligious group, originating in the Israelites or Hebrews of the Ancient Near East. The Jewish ethnicity, nationality, and religion are strongly interrelated, as Judaism is the traditional faith of the Jewish nation. Converts to Judaism, whose status as Jews within the Jewish ethnos is equal to those born into it, have been absorbed into the Jewish people throughout the millennia.
Israel, the Jewish nation-state, is the only country in which Jews make up a majority of the citizens. Israel was established as an independent democratic and Jewish state on May 14, 1948. Of the 120 members in its parliament, the Knesset, currently, 12 members of the Knesset are Arab citizens of Israel, most representing Arab political parties and one of Israel's Supreme Court judges is a Palestinian Arab.
