either you were 4 year old before 9 11 or complete ignorant..
who used to do mosque bombings on almost weekly basis one of the main characters Lashkar e jhangvi and where they were based and getting support at that time Taliban in afghanistan, therefore you need to learn terrorism was there and mosque bombings were there its just new introduction of suicide bombings that had been added after 9 11.
furthermore if you say afghani taliban are good guys then i want to ask do you want mulla umer to lead pakistan as well if no then Shut up we dont need to support afghani taliban for afghanistan as well if something aint good for us then it aint good for the neighbour as well.
also we need to ruthlessly suppress any idea/mentality that a group of thugs can bring down a state we had started with TTP and we should end it with Afghani taliban unless it is done we wont be having peace in pakistan or in the region.
