Since the start of the ongoing Israeli assault on Gaza, antiwar activists have been disrupting the administrative offices, production facilities, and transportation hubs of various weapons manufacturers feeding the Israeli war machine. Targets have included the international branches of Israeli weapons manufacturers like Elbit and multinational corporations that sell to the Israel Defense Force, such as BAE.

As sprawling as those supply chains may be, working up them yields limited opportunities, and activists are largely bound by geography. But it is also possible for activists to work back down the supply chain — not from suppliers to the IDF, but from those suppliers to their other customers.

“These are indeed a secondary market to the trade in heavy weapons that are used to carpet bomb the Gaza Strip and kill thousands of civilians,” says Omar Barghouti, cofounder of the Boycott, Divestment, and Sanctions movement, which advocates nonviolent opposition to the Israeli occupation of Palestine. “But secondary or not, they are important.”
