As the United States has been undertaking an air strike campaign in Iraq and Syria for several weeks, the familiar question in US foreign policy debates reappeared: can airpower alone do the job? Wrong questions, though, lead to wrong answers. Too much focus on military means and ways results in the tacticization of strategy and the neglect of the political context. The United States should strive to defeat the Islamic State strategically, employing military force if necessary, but not by force alone, because weapons can win battles but cannot win wars.
