That ELCA webpage touts a fraudulent series of four maps purporting to show Palestinian losses and Israeli gains since 1946. In fact, it offers free of charge laminated cards bearing that series of maps to those who request them. These maps (which are commonly promoted by anti-Israel activists) utterly distort the history of the region by conflating several categories of "having land" (individual ownership, various forms of political control, etc.), by completely ignoring the historical context of Arab losses and by simply lying. The first map (labeled "Palestinian and Jewish land 1946", see below), shows land owned by Jews or Jewish agencies in white and all other land in the area, including the Negev and Judean wilderness, in green. It claims that the green was "Palestinian land", although, in fact, most of this land was not owned by either Jews or Arabs, was under the political control of the British Empire and was vacant.
Thus a map of the 1947 U.N. partition plan which divided the area between Jews and Arabs appears to show a massive loss of "Palestinian land", reflecting the fact that the largely vacant and inarable Negev desert was partitioned by the U.N. to Israeli political authority. The third map in the series (labeled "1949 - 1967") shows further decline in "Palestinian land" which resulted from Arab losses in the 1948 war. That map fails to mention that that war was a war of aggression started by the Arab states, thereby absolving them of responsibility for those losses. That map also describes the Egyptian-occupied Gaza Strip and the Jordanian-occupied West Bank and East Jerusalem as "Palestinian land". The last map (labeled "2000") inexplicably shows more than half of the West Bank, including the entire Jordan Valley excluding Jericho, as "Israeli land".
