This is true... The. Delegates shid b given diplomatic protection during talks till the time they are safe
unfortunately both the Americans and Afghan puppet regime in Kabul have shown to be untrustworthy in this regard.
Afghan regime wants the violence to continue so that it has American protection forever and it can persecute the Afghans specially the Pashton population. so it either leaks the secret information (death of Mullah Omar),assassinates Afghan taliban delegates as they enter Pakistan on their way to Murree (assassinations of Haqqani family members in Islamabad as an example and other unnamed Afghan taliban on roadside as they entered Pakistan)
Americans think by killing the leadership and keeping pressure will force Taliban to accept the American conditions so they drone strike Mullah Mansoor (waiting until he enters into Pakistan) and other many Afghan taliban delegates over the years. Or they also dont have any interest in peace and would rather stay in Afghanistan (find an excuse to stay) to stop China and Russian influence in the region.
by killing Afghan Taliban leadership inside Pakistan , both Afghan regime and Americans achieve 2 objectives
they can point finger at Pakistan saying Pakistan is housing and protecting the taliban (and make so much noise) and Pakistan cant point out the fact that in order to host the negotiation it has to let the Afghan Taliban leadership safe passage to the meeting point and establish a communication to convey the message.
the reason to stay in Afghanistan continues by ensuring that violence in Afghanistan continues even after the elimination of Al Qaeda and killing of Osama Bin Laden.
you see, the talks in Pakistan never reached beyond second stage, either Americans or Afghan intelligence assassinated the participating Taliban and when the Taliban retaliated through massive attacks then both Americans and Afghan regime cunningly put the blame on Pakistan and this death spiral continues
Pakistan cant win this argument, if it offers official protection to the Afghan taliban delegates to reach the meeting place then both Americans and Afghan regime goons will start bitching at Pakistan saying it is providing support to taliban and protecting them. yes it sounds demented retarded and immature crap talk but thats what is happening for over a decade.
