I shudder to read that you are still thinking how to take a bunch of self-hating “new historians” with no background in history to distort what this and Hamas is all about. Chris D mentions 40 years but the murders have been going on for over 100 years, even before the Jewish State of Israel. 1920, 1937, 1947,1947-1956 and 1956-1967, 1967, 1973 and every thing post 2005 when Israel left Gaza.
