While relatively sensible in other aspects, Prager is a bit of a Israel-interventionist-whore. Which is, you know, cool and everything, but not really my schtick. I can't fault his stats or the graph, though. And, really, the issue seems settled by the fact Israel won a war or two. Palestinians seem to want to wage another one to regain the land without actually doing it.
Anyway, Prager is the guy who got his ass handed to him by asking Chris Hitchens: all things being equal, would he be comforted or alarmed if running into a group of people leaving a church/synagogue/mosque/etc. at dusk on an otherwise empty street. Hitchens responded that he had been in just that situation and - limiting himself only to the Bs - found it entirely disconcerting in Beirut, Bombay, and like four other cities I'm too drunk to recall. Anyway, it was pretty persuasive.
