The United States has been clear from the start about the goals of its campaign against Islamic State.
On September 10, 2014, then U.S. President Barack Obama announced the formation of a broad international coalition to defeat Islamic State, also known as the Islamic State of Iraq and the Levant (ISIL), or Daesh, declaring: “Our objective is clear: We will degrade, and ultimately destroy, ISIL through a comprehensive and sustained counterterrorism strategy.” www.centcom.mil/OPERATIONS-AND-EXERCISES/OPERATION-INHERENT-RESOLVE/,
The military campaign against Islamic State, called Operation Inherent Resolve, issues daily reports on the number of strikes carried out, identifying their targets and precise locations, and detailing the results of each strike. These reports are available to the public online.www.inherentresolve.mil/News/Strike-Releases/,
The U.S.-led coalition also issues monthly reports on civilian casualties, including those caused by coalition attacks targeting IS, and provides details from the investigations into such incidents.www.inherentresolve.mil/News/News-Releases/Article/1329201/cjtf-oir-monthly-civilian-casualty-report/,
