Bias against Israel is the most glaring problem with the new Gaza inquiry that the United Nations Human Rights Council launched last month. The council has appointed as its chief investigator a Canadian lawyer, William Schabas, who has said in recent years that he’d like to see Israel’s prime minister and president hauled before the International Criminal Court. The resolution authorizing his inquiry is crammed with vilifications of Israel, but it makes not a single mention of Hamas, the terrorist group that rules Gaza and that is dedicated in its charter to obliterating Israel and killing Jews. And in the current Gaza conflict that the U.N. purports to investigate, Hamas plays no minor role: It is against the thousands of rockets fired by Hamas and the many miles of attack tunnels — conduits for Hamas death squads — that Israel, in Operation Protective Edge, has been defending itself.
