Despite documentation of the atrocities of the Holocaust, there are those who deny its occurrence. Previously, the Holocaust denial movement had been confined to the western world. Western Holocaust deniers, however, faced with opposition and legal restriction by countries such as the United States, Canada, France, and Germany, have expanded their efforts into many Arab nations, such as Egypt, Syria, and the Palestinian Authority. While Holocaust-inspired anti-Semitism is nothing new in these countries, the on-going Arab-Israeli conflict provides a fertile ground for efforts to promulgate Holocaust denial as a new anti-Semitic propaganda tool. Most disturbing is that many Arab governments and political leaders not only support, but even perpetuate Holocaust denial themselves. With no internal remedies in these Arab countries to suppress deniers' activities, the international community must act to combat Holocaust denial worldwide.
