摘要:Faced with the threat of the Islamic State (ISIS), the United States began its participation in the conflict with Iraq and Syria in August 2014 by employing air strikes to support local efforts against insurgents. In September 2014, President Obama outlined nine lines of effort as a strategy to defeat ISIS, which encompassed governance, economics, security, and development. The security line of effort sought to deny terrorists a “safe haven,” to degrade ISIS leaders, their operational and logistical capabilities, and to prevent access to resources and sanctuaries from which their attacks were prepared and executed.1 This strategy was conducted throughout Operation Inherent Resolve (OIR), whose efforts were the responsibility of the Global Coalition against Daesh, a coalition of more than 60 countries.
