In 2009, I was living in Tel Aviv during Operation Cast Lead. During that offensive, Israel killed about 1,400 Palestinians in Gaza. To take concrete action to bring about freedom and full rights for Palestinians ... I embraced the Boycott, Divestment, and Sanctions movement. The non-violent effort, started in 2005 by a broad coalition of Palestinian civil society organizations, is a call for solidarity from the international community until Israel complies with international law and ends its violations of Palestinian rights. It's hard going though. Seven years later, there have been two more horrific assaults on Gaza. During this time there have been attacks on Israeli civilians too. These are a horrifying symptom of ongoing occupation and repression, as Tel Aviv Mayor Ron Huldai pointed out after a recent attack in Tel Aviv killed four Jewish Israelis. BDS is a powerful way to encourage the state to act. But our efforts have been threatened here in the United States by a nationally coordinated, well-funded strategy financed by the Israeli government and advocacy organizations. Over the last year, 22 states have introduced or passed anti-BDS legislation. Many of these measures make it illegal for states to do business with companies that support BDS. New York Gov. Andrew Cuomo (D) has escalated that strategy with a draconian executive order that would create a blacklist of companies and organizations that choose not to invest in Israel or that advocate for BDS.
