DEMPSY ISIS battle take many years reports,

The Defense Department's inspector general reportedly is investigating whether intelligence reports about the progress of the U.S.-led coalition's campaign against ISIS in Iraq have been altered to be more optimistic. The New York Times reported that at least one civilian employee of the Defense Intelligence Agency (DIA) told authorities that officials at U.S. Central Command (CENTCOM) were improperly reworking intelligence assessments prepared for policymakers, including President Barack Obama. The Times report did not say when the assessments were allegedly altered, nor did it say who may have been responsible. Officials told the paper the investigation was focused on whether military officials had changed the conclusions of draft intelligence reports during a review before passing them on. Government rules state that intelligence assessments "must not be distorted" by agendas or policy views. However, The Times reports that legitimate differences of opinion are both common and encouraged among national security officials. The DIA is one of many intelligence agencies that has produced assessments about the progress of the Iraq campaign. According to The Times, analysts from one agency may make suggestions about another agency's draft analyses, but it is up to the authoring agency to decide whether to adopt those suggestions. The U.S. began launching airstrikes against ISIS in Iraq in August 2014, and did the same in Syria the following month. Last month, however, U.S. intelligence concluded that the terror group was not fundamentally weaker than it was when the aerial campaign began. Officials said that while intervention by the U.S.-led coalition had prevented the collapse of the Iraqi government and resulted in the rollback of some gains made by ISIS in the summer of 2014, the extremist group remained a well-funded army able to replenish its ranks with foreign jihadis as quickly as the U.S. can eliminate them. The intelligence assessment also found that ISIS had expanded to other countries, including Libya, Egypt and Afghanistan.
