An active-duty US Marine captain wrote a stinging op-ed for the Marine Corps Gazette, going through all the problems he sees with the Department of Defense and the Marine Corps in addition to recent failures in Iraq and Afghanistan.

The biggest problem, according to Capt. Joshua Waddell, is “self-delusion.”

“Let us first begin with the fundamental underpinnings of this delusion: our measures of performance and effectiveness in recent wars,” he wrote. “It is time that we, as professional military officers, accept the fact that we lost the wars in Iraq and Afghanistan.”

The active-duty infantry officer, who served with and lost Marines under his command with 3rd Battalion, 7th Marines, in Afghanistan, didn’t come to this conclusion lightly. He said it took several years for him to accept that, with the goal of improving the system.
