In Haaretz, Judith Butler gives a long and personal interview to American-Israeli filmmaker Udi Aloni:

[Aloni:] It’s interesting because when the war on Gaza started, I couldn’t stay in Tel Aviv anymore. I visited the Galilee a lot. And suddenly I realized that many of the Palestinians who died in Gaza have families there, relatives who are citizens of Israel. What people didn’t know is that there was a massed grief in Israel. Grief for families who died in Gaza, a grief within Israel, of citizens of Israel. And nobody in the country spoke about it, about the grief within Israel. It was shocking.

[Butler:] The Israeli government and the media started to say that everyone who was killed or injured in Gaza was a member of Hamas; or that they were all being used as part of the war effort; that even the children were instruments of the war effort; that the Palestinians put them out there, in the targets, to show that Israelis would kill children, and this was actually part of a war effort. At this point, every single living being who is Palestinian becomes a war instrument. They are all, in their being, or by virtue of being Palestinian, declaring war on Israel or seeking the destruction of the Israel.

So any and all Palestinian lives that are killed or injured are understood no longer to be lives, no longer understood to be living, no longer understood even to be human in a recognizable sense, but they are artillery. The bodies themselves are artillery. And of course, the extreme instance of that is the suicide bomber, who has become unpopular in recent years. That is the instance in which a body becomes artillery, or becomes part of a violent act. If that figure gets extended to the entire Palestinian population, then there is no living human population anymore, and no one who is killed there can be grieved. Because everyone who is a living Palestinian is, in their being, a declaration of war, or a threat to the existence of Israel, or pure military artillery, materiel. They have been transformed, in the Israeli war imaginary, into pure war instruments.

Butler discoursed on related themes at a fall 2009 event co-hosted by the SSRC, the Institute for Public Knowledge at NYU, and the Humanities Institute at SUNY Stony Brook, audio and transcripts from which are available here.
