Drawing on ethnographic fieldwork and interviews with citizens and trauma specialists residing within the four kilometer perimeter of Israel’s border with Gaza, this paper explores the politics of Israel’s civil defense siren with a particular focus on the ways in which the siren sound, and lived experience of sound more generally, contributes to localized conceptions of Zionism and national security. It argues that within the political framework of the Palestinian-Israeli conflict, the “Code Red,” or “Tzeva Adom,” siren represents a vehicle of power that is grounded not only in civilian and military authority but also in its coercive and generative capacity to impact the human body both individually and as a collective through its specifically sonic and temporal characteristics. Citizens in this region have specific relationships with this sound, appropriating it for a variety of unofficial purposes. The siren sound, which may resonate more than ten times per day during periods of heightened political tension, constitutes a political and social act, reverberating in multiple registers as its material and sonic qualities collapse distances between state projects, ideological persuasions, and individual bodies. Understanding this sound-power is essential in unpacking the relationship between these Israeli citizens, their state, and the conflict that structures their daily lives. As such, sound-power understood in these terms represents a dimension of Foucaultian governmentality—an organizing practice that produces a particular type of citizen and structures modalities of resistance.
