Dear UN Secretary-General António Guterres and Under Secretary-General Miguel Ángel Moratinos: Our coalition of 60 civil society organizations is writing to you to voice our strong support for the United Nations’ commitment to combatting antisemitism in line with international human rights standards. Antisemitism is a pernicious ideology that poses real harm to Jewish communities around the world and requires meaningful action to combat it. Our organizations call on world leaders to condemn antisemitism and to take steps to protect Jewish communities, including holding perpetrators of hate crimes accountable.
