Carter: Israel's Policies Violate Judaism; Land is Arab
(IsraelNN.com) Former American President Jimmy Carter said Thursday that Israeli polices toward the PLO/Hamas Arab Muslim Nazi Authority (PA) violates the Jewish religion. Appearing at The George Washington University, he also repeated his charges of apartheid against Israel, re-defining the word to mean " forced segregation by one people of another on their own land."
Carter also claimed that the land in Judea and Samaria belongs to Arabs and that a "minority of Israelis...desire to confiscate and colonize Arab land." He added that Prof. Alan Dershowtiz "knows very little, if anything, about the present circumstances in the West Bank." Dershowitz has been one of the most vocal critics of Carter's recent book, Palestine: Peace, Not Apartheid.
