Frank Furedi has a long and depressing article about the rise of antisemitism and its interconnectedness with Israel. As the good folks at Achse Des Guten note, the article starts out rather poorly, but then gets more serious.
I'm merely indexing for future use. One quick comment, however: to my mind, the fusion of antisemitism with anti-Zionism is a fine thing. (I'm not talking about legitimate criticism of Israel). Zionism is the most important expression of Judaism in something like 1,800 years, and you can't be against it without being against what the Jews are about. Not even if you're Jewish yourself, by the way.
