What is really going on here? If they HAVE killed him it occurs to me that the intent never was to gain any of the demands. The demands were purposely made impossible because their real agenda is something other. Perhaps just to suck us in to further conflict in Pakistan. Perhaps to sow discord in Pakestan. Perhaps just to publish their own little group and cause in their local area.
Time to get it. These people kill and kidnap because they are evil to the core.
And kidnapping is the big game - in Hong Kong, in Chechnya, in Georgia, Dagestan and Russia, and in the Phillipines. Now in Pakistan. After kidnapping, they like beheading.....
This is why the Russians have been trying to make Chechnya into a parking lot. America is really late getting into this.
"What is really going on here?"
Don't forget to add irrationality and internal power plays between the kidnappers.
