America’s new ambassador at the United Nations, Michael Waltz, used his first opportunity to address the Israel war against Hamas to berate the Security Council’s one-sidedness on that issue. The council members “opted to convene this high level UN Security Council briefing on Gaza on Rosh Hashanah, the Jewish New Year, knowing full well that that decision excludes Israel,” Mr. Waltz said in his second council speech since the Senate confirmed his appointment as ambassador on Friday. On Monday, the Israeli UN ambassador, Danny Danon, informed the council’s president that Israel would be unable to participate in the council meeting. According to the body’s tradition, countries that are not council members are nevertheless invited to address the body when it takes up issues in which they are involved. During those events country representatives dedicate a large bulk of their speeches to the Gaza war, accusing Israel of failures to end the war or deliver aid to Gazans.
