The reason that the anti-Semitism in Iraq, which is so intense it might better be called a conflagration, can't be discussed in the American news media, which is normally vigilant on this topic, is that it would link the two populations, Iraqis and Jews. This linkage would be detrimental to the fiction that the only players in Iraq, aside from the hapless Iraqis themselves, are the US and its "Coalition", and the US-hating al Qaeda and Muslim fundamentalists generally.
It would surprise a lot of Americans that so many in the Arab world believe that Israel and a kind of collective Jewish intent are behind the invasion and occupation of Iraq; though some Christian fundamentalists are aware of this, approvingly, and assign the Arab antipathy to the evil nature of Islam.
What bothers some of us a lot is the deception. Deception being usually necessitated by immoral objectives, and driven by arrogance, or cowardice.
