Who knows? Nobody does. See my first post... I can also buy that since there are so many Taliban factions, it could be anyone....
But with such a corrupt govt. what can one expect? Its all very confusing... Surely the Talibans who already are criminals may really have done it, but just besides that, do any merceneries have a role? Neither you nor I know what the truth is... so we must not ignore what is going on and look at the complete picture.
Once again I dont follow. You say "With such a corrupt govt, what can you expect". This is preceded by "I can by that since there are so many Taliban factions, it could be anyone". Are you blaming the government for not keeping the Taliban more united?
You are the one raising doubts as to whether the Taleban did it, I expect you to offer more as basis. Atleast one faction of the Taleban has taken responsibility for it, I so no reason for confusion then.
