What's uncertain, however, is whether the U.S. and its allies understand the basis for that moral leadership. Sen. John McCain, R-Ariz., whom my Bloomberg View colleague Frank Wilkinson justly praises for breaking party ranks to support the report's release, spent too much time talking about torture's inefficiency at obtaining valuable intelligence before arguing that what's most important is to safeguard Western values. The entire discussion of efficiency, which permeates the report, is counterproductive if the U.S. wants to express closure and repentance. The message needs to be "What we did was wrong," not "What we did failed to achieve results." Dwelling on the questionable value of information obtained under torture suggests that if more efficient methods of breaking down suspects' resistance can be devised, the U.S. will have no qualms about using them.
