McCain "pressed Hagel on whether he stood by his opposition to the decision to surge U.S. troops into Iraq in 2007."

"Hagel, who once called the surge the 'most dangerous foreign policy blunder in this country since Vietnam' resisted McCain’s repeated attempts to solicit a 'yes' or 'no' answer."

"I’m not going to give you a ‘yes’ or ‘no.’ I’ll defer that to the judgment of history... I did question the surge. I always ask the question: Is this going to be worth the sacrifice? We lost almost 1,200 Americans and thousands of wounded. Was it required? Was it necessary? I’m not sure. I’m not that certain that it was required."
