Not long ago, the so-called Islamic militants Boku Haram kidnapped hundreds of girls then announced they were for sale.
Now the self-styled Islamic State in Iraq and Syria is in the news selling as "spoils of war" captive females they claim converted to Islam in order to marry Islamists.
While it's not clear what established governments are willing to do to protect women from being treated as property (U.S. planes apparently engaged in search activity), it's evident that private individuals are willing to take steps to free captives.
This isn't to say that fascist-government-sponsored sex slavery is new (it isn't), or that established governments do better (if Russia is "established", definitely not), or that it can't thrive where local law is otherwise effective (if we doubt law in the U.S., there's at least a tradition of the rule of law in Canada, no?). There's room for improvement everywhere, apparently.
