This organization is doing a number of things to try to lessen the violence in Israel and Gaza. They have gotten over a hundred performers to pledge not to perform in illegal settlements. They are also calling on TIA Creff to divest from the occupation. They have organized a rabbinic counsel to speak out for justice for all people.
Do you think any of these activities will be useful? What else could they do?
