Pakistan's North West Frontier around the Khyber Pass has become a Taliban playground. They now control over 500Kms of frontier and its environs bordering Afghanistan following a series of disasterous "peace agreements" with the Pakistan Government. And what they don't control they influence.
The latest domino is Hangu. Seven days of operations by the Pakistan Army have finished with an agreement under which they will pay compensation and withdraw. The Taliban have agreed to recognise the government's authority, stop attacks on government security forces and refrain from running parallel government and legal systems. To date they have made such agreements in half a dozen other territories - and stuck to none of them.
