The director of national intelligence affirmed rather bluntly today that the U.S. intelligence community has authority to target American citizens for assassination if they present a direct terrorist threat to the United States. We take direct actions against terrorists in the intelligence community; if we think that direct action will involve killing an American, we get specific permission to do that," Director of National Intelligence Dennis Blair told the House Intelligence Committee. "Whether that American is involved in a group that is trying to attack us, whether that American ... is a threat to other Americans. Those are the factors involved." Blair explained. According to U.S. officials, only a handful of Americans would be eligible for targeting by U.S. intelligence or military operations. The DNI said that Internet and social media sites have become critical to terrorism recruitment efforts. "The homegrown radicalization of people in the United States is a relatively new thing." Blair said U.S. intelligence was rapidly working to counter the emerging problem.
