People talk about the term "the new anti-Semitism" and there is some debate on whether or not it is real. I'm not going to weigh in completely on whether or not new anti-Semitism is prevalent today or not, but check out this comment. It's on a thread about Oliver Stone's latest controversial remarks claiming that the Jews control America, including the media.
Now on the one hand people tell us that American Jews and Israel don't have anything to do with each other. People criticize Israel but love Jews, they say, because Israel is it's own state that makes it's own decisions. But take a look at that comment again. Why would Israel's actions have anything to do with a perception about American Jews and their "control" over America? Shouldn't the Jews' actions and Israel's actions have nothing to do with each other?
It sounds like the critics of Israel (anti-Semitic or otherwise) try to disassociate Israel from Jews in general, but only when it suits them. When they need to excuse anti-Semitism in America, though, they will blame Israel for it. Whether this indicates the presence of "the new anti-Semitism," though, I cannot say for sure. You be the judge.
