The Zionist movement was non-religious from the start, if not anti-religious. Almost all the Founding Fathers were self-declared atheists.
In his book "Der Judenstaat", the original charter of Zionism, Theodor Herzl said that "we shall know how to keep (our clergymen) in their temples." Chaim Weitzman was an agnostic scientist. Vladimir Jabotinsky wanted his body to be cremated - a sin in Judaism. David Ben-Gurion refused to cover his head even at funerals

At one stage of its development, the PLO called for the creation of a "Democratic secular state, where Muslims, Jews and Christians will live together".

According to the authoritative Israeli Government Bureau of Statistics, only 8% of Israeli Jews define themselves as "Orthodox"
(Haredim), 9% as "religious" (meaning Religious Zionists), 45% as "secular, non-religious" and 27% as "secular, traditional"

I have been haunted by a nightmare: that the Israeli-Palestinian conflict would change from a national to a religious confrontation
