Even before the birth of the modern state of Israel, Jews have stood accused of not possessing sufficient loyalty to the nations where they reside. The contemporary manifestation of this canard, however, almost always centers on the notion (advanced by Greenwald) of dual loyalty — a charge that Jews are more loyal to Israel than their own nation.

Often, such charges of dual loyalty are infused with a narrative imputing enormous power to Jewish communities, which typically represent a tiny fraction of the overall population. Such a synthesis of disloyalty on the one hand and exaggerated power on the other allows the accuser to charge the Jewish community of working to undermine their nation, often alleging that such Jews are dangerous aliens who represent nothing short of a Fifth Column.

Yet, the new breed of Judeophobic polemicists such as Glenn Greenwald, whose blog was initially called “Unclaimed territory,” style themselves as bold new thinkers - brave dissidents who are willing to explore “taboos” about the national loyalty of Jews and their corrosive effects on the American body politic that others dare not touch.

His narrative, however — full of poisonous, old, lethal tropes about the dangers of collective Jewry to the body politic — is as ancient as the Jewish Diaspora itself.
