WASHINGTON - US Secretary of State John Kerry delivered a full-throated defense of Zionism at the United Nations on Wednesday night.Commemorating forty years since Chaim Herzog, then Israel's ambassador to the UN, rebuked the body's general assembly for its efforts to equate Zionism with racism, Kerry effectively equated anti-Zionism with racism– a scourge, he said, that remains as "abhorrent" and widespread in 2015 as it was in 1975.Herzog's task that year was to deliver Israel's response to Resolution 3379, originally crafted to condemn historic racist and colonialist trends. The effort quickly transformed into a vehicle to undermine the founding principles of the Jewish state, Kerry said, and passed on "a day of infamy" when "the abomination of anti-Semitism was given the appearance of international sanction."Those who supported the proposal, Kerry said, lived in "willful ignorance of history and truth." Referring to Israel as the "historic homeland of the Jewish people," the secretary said that hatred of Jews remains an international challenge in several international bodies."Too many outside this room fail to realize the global reality of anti-Semitism today," he said.
