The thing to notice about this cartoon— which the Anti-Defamation League reports is circulating among white supremacists– is that if you removed the kippot from Obama’s and McCain’s heads and changed the caricature of the stereotyped Jew to a caricature of, say, Ehud Olmert (like this one), it could easily appear on any number of “anti-Zionist” leftwing websites– perhaps drawn by the execrable Carlos Latuff, whose works are so lovingly archived by Norman Finkelstein.
As the ADL notes, the image is very similar to some cartoons that have appeared recently in the Arab and Muslim worlds.
