Khawaja Khalid Farooq

Britain's prime minister David Cameron once accused Pakistan of facing both ways in the fight against terrorism. More recently he said we must 'stand together'. Gavin Esler speaks to Khawaja Khalid Farooq, who until very recently was head of Pakistan's National Counter Terrorism Authority. Does David Cameron's change of tone represent a new understanding that Pakistan is bearing a heavy burden of fighting and suffering great losses? Or is it part of a Western panic that Pakistan may be in such trouble that public criticism is no longer of any use?
