"When the Anti-Defamation League (ADL) first released its 2003 report Unraveling Anti-Semitic 9/11 Conspiracy Theories, we said then that these conspiracy theories were likely to form the basis of a new anti-Semitic canard that would linger for decades and be used to demonize Jews and Israel. Three years later, this prediction has proven to be true, as these theories gain more currency around the world, particularly in Muslim and Arab countries.

Blaming Jews for manipulating world events for their own benefit is not new -- it is at the very root of anti-Semitism. These theories are a continuation of age-old allegations that there is a secret and powerful group of Jews who regularly plot deceitful, sinister actions in order to gain power. These allegations were behind the fabricated anti-Semitic publication, The Protocols of the Learned Elders of Zion. More than a century later, Jews are still fighting against this dangerous scapegoating, which has made them a constant target for hatred."
