Official anti-Semitism is on the rise in Muslim countries of the Middle East, fueling long-term hostility to Israel, a study found. Israel’s Intelligence and Terrorism Information Center published a study this week arguing that in Iran and Arab states — even those that have recognized the Jewish state — officially sanctioned statements of anti-Semitism with a Muslim slant are increasing, often as a means of diverting internal dissent from the government. One salient example is Holocaust denial twinned with allegations that Israel is practicing a “real” holocaust against the Palestinians. Anti-Semitism tends to rise in parallel to progress in diplomatic rapprochement between Arab regimes and Israel, calling into question the long-term efficacy of such accords. The study singled out Iran as a country whose anti-Semitism poses a potential threat to Israel’s existence, given Tehran’s supposed nuclear program. “Anti-Semitism supported by a state which publicly adheres to a policy of genocide and is making efforts to arm itself with non-conventional weapons which will enable it to carry out that policy is unprecedented since Nazi Germany,” the study said.
