More than 50 intelligence analysts at Centcom have formally complained that reports on the Islamic State and the Nusra Front - Al Qaeda's Syria branch - have been repeatedly altered by senior intelligence officials to fit with the Obama administration's insistence that the US is winning the war against the two militant groups. Former CIA deputy director Michael Morell explained on "CBS This Morning" how serious these allegations are. "One of the key aspects of the policymaking process in the United States is that analysts get to say what they think ... if there is truth that somebody has been meddling with their analysis, I think somebody needs to lose their job over it." A written complaint was sent in July by two Centcom senior analysts to the Department of Defense Inspector General. Eleven individuals knowledgeable about the details of the complaint [say] crucial parts of intelligence reports were taken out, analysts were subject to an environment in which they did not feel able to give a candid assessment of the situation in Iraq and Syria, and sometimes reports seen as being too negative were sent back to analysts. One source alleges that when [analysts] brought concerns to Centcom leadership, they were urged to retire, and some agreed to leave. In late July, the Associated Press reported that assessments by the CIA, the Defense Intelligence Agency, and others found that the Islamic State, also known as ISIS or ISIL, is no weaker than it was when US bombing began in 2014.
