Was School Massacre the Taliban's Revenge for This?

The Peshawar school massacre follows pledges by the Pakistani Taliban to retaliate for an offensive targeting militants in North Waziristan that was launched in June. Here's what NBC News' Wajahat S. Khan found when he visited two towns that had been devastated by the offensive on Nov. 14. MIR ALI, Pakistan —A television studio for suicide bombers, a market offering car bombs in a variety of colors and a secret tunnel filled with rotting corpses under the local mosque. These were aspects of daily life in the militant-controlled mountain area of North Waziristan, according to Pakistan's military.
