Lieutenant General Greg Newbold (Ret.) explains "Why Iraq Was a Mistake" in this Time Magazine column:

"From 2000 until October 2002, I was a Marine Corps lieutenant general and director of operations for the Joint Chiefs of Staff. After 9/11, I was a witness and therefore a party to the actions that led us to the invasion of Iraq--an unnecessary war. Inside the military family, I made no secret of my view that the zealots' rationale for war made no sense. And I think I was outspoken enough to make those senior to me uncomfortable. But I now regret that I did not more openly challenge those who were determined to invade a country whose actions were peripheral to the real threat--al-Qaeda. I retired from the military four months before the invasion, in part because of my opposition to those who had used 9/11's tragedy to hijack our security policy. Until now, I have resisted speaking out in public. I've been silent long enough."
