Don't know if true, but been hearing rumors from contacts in Pakistan that behind the scenes, the civilian political leadership in Pakistan seems to be a lot more ready and willing to go to war than the Army which is apparently trying to reign in expectations.
There's serious consideration that if the Talibs don't take action, Pakistan may take far more drastic actions along the border, such as building a permanent 300 meter kill zone.
Again, this is what I've been told.
No evidence of it, but my contact worked as a junior Intel officer a while back.
