Pakistan is not the single country works for the rights of Kashmiri muslims, entire muslim world supports them. Armed struggle is indigenous movement and Pakistan is not responsible for it. For your information this attack was done by Jaish Muhammad SAW and they are directly supported by Afghan Taliban. It is clue for your occupied forces to quit Kashmir otherwise NATO withdrawl will lead to new era of militancy in J&K.
And that will be followed by a bigger insurgency in Balochistan and NWFP. It doesn't matter how many insurgents you send now. 80% of them die at the Border, the rest are found soon and burried in unmarked graves.
