This article addresses the phenomenon of collaboration and societal reaction to it in the Israeli-Palestinian context. The authors identify a "triangle of betrayal": the Palestinian collaborators' betrayal of their communities; the betrayal of the communities who often use the label of collaboration as a pretext for abuses; and the betrayal of the Israeli government who often receives services from the collaborators and later abandons them to their fate. A transitional justice framework is proposed as a potential means to respond to this complex legacy.Betrayal is the only truth that sticks (Arthur Miller, After the Fall)The Israeli "disengagement" from Gaza is far from a full end-of-conflict initiative, yet it can be seen as a "simulation" of limited peace, as an exercise-or improvised dress rehearsalin what an end, or a substantial transformation, of the Israeli-Palestinian conflict may look like. When the fog of violence clears, the actors are exposed in their predicted roles: Jewish colonial settlers reluctantly pulled from their houses back to Israel, Israeli soldiers withdraw to new lines, Palestinians who suffered under these soldiers and settlers would be able to enjoy a slightly higher level of freedom, and civilians inside Israel fear rocket attacks from liberated Gaza. Dilemmas and concerns abound-the fate of the houses left behind, security arrangements, control of borders. Yet in the hundreds of journalistic pieces, think-tanks' position papers and legal analyses, few have paid attention to an awkward actor, which does not fit clearly in our predicted categories-Palestinian collaborators.
