Poster: Obstacle to peace

This one requires some documentation.

Here are the best numbers I could find in Arabs killing Arabs since 1948, mostly relying on Wikipedia.

War	Year started	Low estimate deaths	High estimate deaths
Algeria civil war	1954	150000	800000
North Yemen Civil War - Egypt	1962	100000	126000
Black September, Jordan	1970	2000	25000
Sahara war	1975	10000	24000
Lebanese Civil War	1975	130000	250000
Libya Egypt war	1977	500	500
Iraq under Saddam	1979	600000	800000
Hama massacre, Syria	1982	17000	40000
South Yemen civil war	1986	10000	10000
Iraq invasion of Kuwait	1990	1000	2000
Yemen civil war	1994	7000	7000
Yemen - Sa'adah Insurgency	2004	5000	8300
Hamas-Fatah fighting	2006	600	600
Lebanon Camps	2007	275	275
TOTAL		1033375	2093675

As you can see, estimates vary wildly for many of these events. I pretty much took the midpoints for the purposes of the chart, estimating about 1.5 million Arab deaths. (There have been perhaps 60,000 Arabs killed in all the Arab/Israeli wars combined including the intifadas.)  I tried not to include Kurdish deaths nor those Arabs killed by the French during the Algerian war - much of that war was a civil war as well. I also did not include the Iran/Iraq war at all since that was not Arab on Arab violence, and Muslim on Muslim deaths is an entirely different set of numbers.
