In the article, Crabapple describes Guantanamo as "a factory consuming money, morals, and decades of human life." The counterpoint that governments (plural, not just the US) are making is that Guantanamo is now a factory for seething hatred that, given the opportunity, would produce new, fanatical warriors for violent jihad. No country wants to take these men on because of this perceived risk. Honestly, given the nature of indefinite detention, most humans probably would harbor a deep-seated hatred for their captors. I'm not saying it's right, but that's the other side of the argument.
