The president's counterterrorism adviser now says civilian deaths are inevitable in the U.S. hunt for terrorists.
John Brennan's comments on ABC's "This Week" are in stark contrast to those he made in June 2011. He claimed then that in the prior year there hadn't been "a single collateral death because of the exceptional proficiency, precision of the capabilities we've been able to develop." His remarks were sharply challenged at the time by human rights groups and anti-war advocates.
On Sunday Brennan said there had been a period of time where the U.S. "had no information about a single civilian being killed." But, he added, "unfortunately in war there are casualties, including among the civilian population." He said "sometimes you have to take life to save lives."
