They always say that truth is the first casualty of war.

What they don’t say is that senior officers in the Pentagon have a long history of lying to their superiors in civilian leadership. Maybe they should:

When Islamic State fighters overran a string of Iraqi cities last year, analysts at United States Central Command wrote classified assessments for military intelligence officials and policy makers that documented the humiliating retreat of the Iraqi Army. But before the assessments were final, former intelligence officials said, the analysts’ superiors made significant changes.

In the revised documents, the Iraqi Army had not retreated at all. The soldiers had simply “redeployed.”

Such changes are at the heart of an expanding internal Pentagon investigation of Centcom, as Central Command is known, where analysts say that supervisors revised conclusions to mask some of the American military’s failures in training Iraqi troops and beating back the Islamic State. The analysts say supervisors were particularly eager to paint a more optimistic picture of America’s role in the conflict than was warranted.

In recent weeks, the Pentagon inspector general seized a large trove of emails and documents from military servers as it examines the claims, and has added more investigators to the inquiry.

Staff members at the House Permanent Select Committee on Intelligence are also poring over years of Centcom intelligence reports and comparing them to assessments from the Central Intelligence Agency, the Defense Intelligence Agency and others. The committee is not just examining reports about Iraq, Syria and the Islamic State, but also about Afghanistan and other areas under Centcom’s purview. The insurrection inside Centcom is an important chapter in the story of how the United States responded to the growing threat from the Islamic State. This past summer, a group of Centcom analysts took concerns about their superiors to the inspector general, saying they had evidence that senior officials had changed intelligence assessments to overstate the progress of American airstrikes against the Islamic State, also known as ISIS.

………

Senior lawmakers have begun their own inquiries into the military’s intelligence apparatus. Representative Mac Thornberry, the Republican from Texas who is chairman of the House Armed Services Committee, said in an interview that his committee was examining intelligence assessments from Centcom and other military commands to see if there was a systemic problem of dissenting voices being muffled by senior military commanders.

………

That investigation was prompted by complaints this past summer from Centcom’s longtime Iraq experts, led by Gregory Hooker, the senior Iraq analyst. In some ways, the team’s criticisms mirror those of a decade ago, when Mr. Hooker wrote a research paper saying the Bush administration, over many analysts’ objections, advocated a small force in Iraq and spent little time planning for what would follow the invasion.

Lawmakers originally said that the Centcom investigation would be completed in weeks. But Pentagon investigators have found the work painstaking and it could span months. In addition to determining whether changes were made to intelligence reports — and if so, who ordered them — the investigators, like the staff members of the House intelligence committee, are studying reports from other intelligence agencies produced at the time to determine what was actually occurring in Iraq and Syria when the reports were written.

This sort of sh%$ needs to stop.

This is simply unacceptable. It is antithetical to the idea of civilian control of the military.

Anyone in the chain of command for these actions need to be sent stateside now.

Once the investigation is done, any responsible for this should be court martialed. Anyone who should have known and did not make a report to the inspector general should be fired.

This was a deliberate attempt to deceive the SecDef and the President. It cannot, and should not, be tolerated.
