Imran Khan blurted it out.

The 40% success rate against Taliban in military operation in North Waziristan suggested by Gen Kayani in a secrete meeting with Nawaz Sharif and Imran Khan was a clever ploy. He knew that one of them sooner or later would blurt it out sending a message to the Americans that such action would not have had the desired results. In reality, the Pak army is strong enough to crush any insurgency. There is a message for Imran Khan also. He should be careful when facing anchors like Hamid Mir who is known for his anti-army stance.
