Obeying the orders of a political organization. Or are you disregarding all the reports that the punishment was ordered by a "Taliban commander?"
The so-called "Taliban commander", or "Taliban fighter" was the woman's husband. The press makes it seem like a tribunal of Osama bin Ladens convened by teleconference using their iPhones from all over Afghanistan, to put the woman on trial, and some masked guy was hired to carry out their sentence while the poor husband watched in horror. Then when you read the press reports in detail, there's a somewhat different story .... yes, the guy was Taliban 14 years ago when the girl was given to him as "blood debt". A large chunk of the population of Afghanistan, presumably, was Taliban 14 years ago. They had a civil war and the Taliban almost won, remember?
Of course, the Taliban is a brutal group and it wouldn't surprise me at all that they would sanction such barbaric punishments against women. However, in this case, like I said, the fact is no political organization was involved. Just families with a radical Islamic ideology and families who don't respect women's rights.
You may as well say that "The Republican party sentenced" a woman to be abused if her Republican husband abused her.
How could predator drones or U.S. special forces possibly stop this kind of thing from happening? They can provide security, possibly, but ultimately this was a crime, surely it is illegal in Afghanistan to enslave and butcher a woman like this? If so, police and crime-fighting is the way to stop this behavior. If not, then it's impossible to stop this behavior until the people of Afghanistan decide they care about women's rights enough to pass laws against this kind of thing.
