Just to preempt the usual “but torture works” morons who like to crawl about: There are plenty of things that humanity has done in warfare that “worked”. Chemical weapons “worked”. Concentration camps “worked”. Genocide “worked”. And nations which practice those things today are considered evil and worthy of destruction.
Now, those of you who live in consequence-free mindsets where the United States can “do no wrong” ought to come out here into the real world once in a while.
