In 2005, Palestinians called on the world to boycott Israel until it complied with international law. What if we had listened?

Exactly 15 years ago this week, I published an article in the Guardian. It began like this: Enough. It’s time for a boycott.

Back in January 2009, Israel had unleashed a shocking new stage of mass killing in the Gaza Strip, calling its ferocious bombing campaign Operation Cast Lead. It killed 1,400 Palestinians in 22 days; the number of casualties on the Israeli side was 13. That was the last straw for me, and after years of reticence I came out publicly in support of the Palestinian-led call for boycott, divestment and sanctions against Israel until it complies with international law and universal principles of human rights, known as BDS.
