n Lebanon, diverse sociopolitical projects have sought to mend the wounds, repair the cracks, and overhaul the loss of the devastating civil war (1975–90). Experts and technopolitics have featured centrally in almost all of them. In my anthropological research on expertise on peace and crisis in Lebanon, I explore how, in the decades after the war, an abstract ideal of peace gave way to a distinct space occupied by diverse groups of experts. I analyze how a previously political aim was transformed into a professionalized field around which specialized knowledge domains were developed and technopolitical practices deployed. In this essay I briefly explore this new architecture of expert power based on the technopolitics of peace (and war) in the contemporary Middle East.
