Yeah sure ISI supported terrorist Afghan Taliban until 9/11 happened and they started a war against the same people who were previously "good terrorists". In response TTP was born
This good terrorist bad terrorist, Afghan, Pakistani Taliban, pre and post-9/11 you're oversimplifying.
To blame like that is to miss out key details and definitive elements of the story. A few facts, questions rather for you to consider before making your judgement:
What is the difference between the TTP and Afghan Taliban, and some sub factions?
What is the difference between the Afghan Taliban post-9/11 and 90's era?
What was the political landscape of Afghanistan at the time, right from the exit of the Soviets, carrying into the Njibullah government, and the two civil wars? I can tell you that people ruled Kabul once that made Taliban look like fairies and saints.
Origins of the taliban in 1994 and the reasons for their widespread support and successful campaign.
Who are the Northern Alliance and what is their significance in post Soviet Afghanistan and whom do they represent and who do they hold grudges with?
Ethnic and sectarian colours to the conflict, right from the civil war, till today? The time of the soviet invasion, seeds were sown once again of an old divide between people, triggered between mistrust and betrayal between opposing factions and tribes.
How did the US' change the conflict?
How did the presence of foreign troops once again, change the entire equation not just over there, but in Pakistan too.
Answer even half of these questions adequately and you would not so confidently blame the ISI, trust me.
I wish we Indians were given as much leeway as him, to call another member a "bastard" in seven continous posts, without even getting a negative rating. (To say nothing of a ban.)
I've been considering doing it myself, banning for all the insulting he's been doing here. But at the risk of being labelled a traitor again. If any member has reported him, I'll let another mod take care of it. General rule of thumb I use is, if I've replied to a thread, I'd think twice before moderating it, and if I've become involved in a tussle like this, I'll leave it for someone else to deal with. Again avoiding the risk of seeming like a tyrant and a hypocrite.
