The U.S. Constitution forbids the government to establish a religion here. The prupose was to prevent the various states from enacting legislation that required everyone to be a member of the church of England (now the Episcopal Church of America). Our Constitution was never intended to authorize freedom from religion as many atheists now claim. Israel was/is a nation founded by YHWH, not by men. Worship of YHWH and acceptance into the nation of Israel are one and the same by edict of YHWH. There fore, it is perfectly sensible for the modern nation of Israel to adhere to the requirement that its citizens accept fealty to the nation of Israel and accept YHWH as their God exclusive of all others. It is perfectly acceptable to enact the 613 laws of YHWH into an Israeli 'Constitution" and use that as the standard for secular law in Israel. Furthermore, it is permissible for Israel to revoke/deny the citizenship of persons living in Israel who refuse to accept those conditions of citizenship. It is not necessary to throw them out bodily for refusing--certain requirements could be imposed on them that would allow them to remain in the custody of their families who remain citizens--but their right to vote, own firearms, receive free medical and education benefits could be suspended or revoked. Their right to publish their opinions could be curtailed, etc. Israel is uniquely Jewish and must remain so in order to be Israel and to serve YHWH.
