On June 24, the SUSTAIN Campaign, Free Palestine Alliance, and the Berkeley Students for Justice in Palestine sent a letter to the Caterpillar Corporation asking that they halt all sales of equipment to the Israeli Defense Forces (IDF). To date, Caterpillar has not responded. A international campaign to expose Caterpillar's complicity in Israel's war crimes and pressure the Peoria, Illnois based equipment manufacturer to stop all sales to the IDF is now underway.
