With the introduction of President-elect Barack Obama's intelligence team on Friday, the United States is poised to enter what might be considered the second phase in the counter-terrorism campaign launched after the Sept. 11 attacks.

Obama and his spy chief nominees have promised a dramatic break with the policies of the Bush administration, largely by focusing attention on what they intend to undo -- including shutting down the Guantanamo Bay, Cuba, prison complex and ending the CIA's use of "enhanced" interrogation techniques.

But the incoming administration has been less clear about what it will erect to replace those programs, which drew condemnation from much of the world but often were cited by Bush administration officials as key to keeping the country safe.
