Appearing on AC360 Later with CNN's Anderson Cooper, Christiane Amanpour asked David Kay, former chief U.N. weapons inspector in Iraq, about the efficacy of air strikes against Iraq in 1998.
"I tell you, at the time of the strike I confess I was a skeptic," he said. "Blowing up empty buildings in the middle of the night didn't strike me as terribly effective."
But Kay said his mind was changed when he visited Iraq years later.
"We carried out a vast range of interviews with senior officials," Kay said. "Their claim was that it fundamentally shook Saddam's confidence. ... What he cared most about was survival. And he saw those institutions of coercion that he used to control the society and his own military being threatened. He said, 'Ah,' and he did draw back at that point."
