ISLAMABAD (Reuters) - The massacre of more than 130 Pakistani school children by Taliban gunmen was a chilling reminder of Hillary Clinton's warning to Islamabad in 2011 that "you can't keep snakes in your backyard and expect them only to bite your neighbours".
Now, as Pakistan reels in horror at the bloodshed in a military-run high school in Peshawar city on Tuesday, pressure will mount on politicians and generals who have long been tolerant of militants they counted as strategic assets in their rivalry with India and jostle for influence in Afghanistan.
