ABC News' George Stephanopoulos

"[Ken Adelman] called your administration 'among the most incompetent administrations of the post-[World War II] era,'" Stephanopoulos said to Cheney. "'Individually, each team member had serious flaws; together they were deadly dysfunctional.'" Cheney, staring at Stephanopoulos as he spoke, then smirked and said, "I haven't seen the piece, I'm not gonna comment on it, George."

When pressed, Cheney added, "Well, I think there's no question, but ... it's a tough war, but it's also the right thing to do. And it's very important that we complete the mission. I just fundamentally disagree."
