General: "unimaginable" to allow North Korea capability to nuke U.S.

Comments yesterday at the Aspen Security Forum from Marine Gen. Joseph Dunford, the chairman of the Joint Chiefs of Staff, via Politico's Nahal Toosi:

"Many people have talked about military options with words like 'unimaginable'... I would probably shift that slightly and say it would be horrific... [A]nyone who's been alive since World War II has never seen the loss of life that could occur if there's a conflict on the Korean Peninsula.

"[I]t is not unimaginable to have military options to respond to North Korean nuclear capability. What's unimaginable to me is allowing a capability that would allow a nuclear weapon to land in Denver, Colorado. That's unimaginable to me. So my job will be to develop military options to make sure that doesn't happen."
