swat was a princely state till 60s or 70s (not sure). when it became a part of pakistan their law was abolished. since then they have been demanding their very same law which was simpler and cheaper. now there is no such demand in other parts of pakistan. and if there is, its only restricted to few ppl. talibans can only spread their influence where they ll find some public support which apparently they are failing to find.
they did try to establish their influence in bajur but bec they lacked local support they were finally crushed. same goes for other parts of fata where locals have formed lashkars to fight talibans.
now bec the main demand of locals have been met, so if talibans dont lay down their arms gov will be in a much better position to take action against them. locals will be on gov side. and i think taliban won just lay down their weapons and finally gov will have to take some action. but this was a necessary step to win against them.
and yes you are rit, if gov would have met local demand of shariah law a dacade back then today we would not be seein ourself negotiating with taliban.
thanks sir for that elaborate answer there much appreciated but there again comes up the question in your very post you said that the taliban did try to implement its sphere to influence in other pasts also unsuccessfully though
then dosent it prove the intentions of the taliban clearly that they are looking much beyond for now they dont have support but then in the future they would pose a direct threat to the GOP and then they would be much stronger as they already have a place now to increase their influence and power aka swat province isnt it more logical then to get rid of the taliban and implement the sharia law without them arnt pakistan sowing its seeds for a bigger conflict later.
