Following U.S. excursions in Iraq and Afghanistan, there is renewed interest in the no-fly, or air exclusion, zone as a coercive instrument. Yet, there is no conclusive agreement over the coercive efficacy of air exclusion zones. Thus, the goal of this study is determine if air exclusion zones are an effective and efficient coercive alternative to major combat operations and, if so, under what conditions. To answer this question, the study compares and contrasts three recent cases, Iraq, Bosnia and Libya, where air exclusion zones were the primary means of coercion. Following this examination, the study concludes that, given certain circumstances, air exclusion zones are an effective and efficient coercive alternative to major combat operations.
