I guess, nobody wants to turn the topic into a pi$$ing contest.
To start with, both these letters are well qualified to serve as sanitary paper with immediate effect. No professional army officer would indulge into this kind of communication, ally or foe notwithstanding.
As to what's happening in the frontiers, I don't think that the PA commanders have learnt anything from Bajaur, else, Buner wouldn't have been swarmed with the Talibs. The only respite is that they have started retreating. However, everybody related to Pakistan and its destiny has the rights to question the PA as to why did it happen in the 1st place. A taxpayer has rights to know that even after paying his fair share for the betterment of the country, why has its army allowed non-state actors to seize control on territories whych belong to Pakistan and not any foreign mercenary? All territory which are parts of Pakistan are sacrosanct and HAVE to be protected, exactlly why we raise and maintain an Army. You can't really keep blaiming the FCs day and night and twice on Saundays.
Edit: Pari, nice to see you here.
