In an article:
http://asbarez.com/94959/does-samantha-wield-the-power-to-set-obama-on-the-right-course/, it is hoped that US foreign policy can be "corrected" and set on a "moral" path:
Foreign policy decisions are not based on right or wrong, but rather on interests. [Samantha] Power herself makes that case (A Problem from Hell: America and the Age of Genocide. If a policy on some event happens to conveniently coincide with what is considered right, most parties are happy. When a foreign policy decision ignores what is right, many are outraged – but outrage for its own sake is not productive.
How do we know that Power herself didn't use a preoccupation with genocide for her own personal gain? After all, who would counter her expose' on ignoring genocide. Power extracted as much as she could from the topic, and those intimately associated with it, and has moved on. There is a clear lesson here.
