What's wrong with the word "antisemitism"?

Obama's now criticized Ahmadinjad's speech at Durban II. I'm grateful so many nations have been highly critical of Ahmadinejad. But in news reports and public condemnations, something is curiously missing. We get "appalling and objectionable." HRW said "hate-filled." The Norwegian PM called it "incitement to hatred." But funny that the word antisemitism is missing from all of this. I've yet to see it.
