Ze'ev is known for his strong opposition to the evacuation of Jews from Israeli settlements. To advance this cause, he established the Knesset Caucus for Israel, Judaism, and Global Ethics, and presented legislative proposals to prevent the evacuation of settlers against their will. Among the other laws initiated by him are the Law to Increase Child Allotments, the Law to Punish Terrorists, the Abortion Law, the Incitement Law, and the Law to Recognize the Rights of Jewish Refugees from Arab Lands.
