One thing that concerned from the beginning was ISPR's ridiculous statement on the first day that Dir has been cleared and Buner would be cleared in 7 days. They're still operating on the assumption that they're fighting regular forces without the ability to melt into the population or hide in the mountains or civilian houses. This fight will last years.
Any military's PR department will always give the most optimistic view. If it does anything else it would harm the morale of its own soldiers!
