From the perspective of someone who has worked with U.K. and U.S. intelligence agencies, the damage done by CIA’s program is so vast that it is hard to fully understand.
No post-9/11 official government program was hotly debated, or as ultimately reviled, as the CIA’s use of “enhanced interrogation techniques.” The CIA's program engendered a robust moral, empirical and legal debate. Today, it still raises questions about congressional oversight, accountability, international law, and human rights at moments of supreme emergency. The military also struggled with coercive interrogation during the early years of overseas counterterrorism operations. And as it seeks to bring former CIA detainees to trial for war crimes, it continues to deal with the lasting consequences of the CIA's program.
