Based on extensive case evidence, Robert Mandel assesses the short-term and long-term, the local and global, the military, political, economic, and social, and the state and human security impacts of brute force. He explicitly isolates the conditions under which brute force works best and worst by highlighting force initiator and force target attributes linked to brute force success and common but low-impact force legitimacy concerns. Mandel comes to two major overarching conclusions. First, that the modern global application of brute force shows a pattern of futility-but one that is more a function of states' misapplication of brute force than of the inherent deficiencies of this instrument itself. Second, that the realm for successful application of state-initiated brute force is shrinking: for while state-initiated brute force can serve as a transitional short-run local military solution, he says, it cannot by itself provide a long-run global strategic solution or serve as a cure for human security problems. Taking the evidence and his conclusions together, Mandel provides policy advice for managing brute force use in the modern world.
