[DAWN] Former army chief retired Gen Pervez Musharraf believes that one of the reasons why the country’s security challenges have become almost insurmountable now is because his successor, retired Gen Ashfaq Parvez Kayani, was too scared to take action against militants.In an interview with Dawn on Tuesday, Gen Musharraf said that it was Gen Kayani’s own reluctance — and not poor judgement — that caused him to not launch an operation against the Taliban.
