 Their 2004 study of 13 Israeli textbooks and 9 Palestinian textbooks found that "neither side's books tell the story of the conflict from the other's viewpoint, both ignore the other side's suffering and each counts only its only victims".In 2002, the United States Congress requested the United States Department of State to commission a reputable non-governmental organization (NGO) to conduct a review of the new Palestinian curriculum.The Israel/Palestine Center for Research and Information (IPCRI) was thereby commissioned by the U.S. Embassy in Tel Aviv and the US Consul General in Jerusalem to review the Palestinian Authority's textbooks.
