Karan has taken a broad view of terrorism and not confined himself to the subject in a narrow sense. He has commented quite freely on issues which may lie more in the realm of foreign and defence policies. Having spent long years in the Intelligence Bureau, he is well-qualified to comment on these issues. However, he would have carried more conviction if he had discussed some of the issues in greater detail and substantiated his comments with more facts. For example, he makes a rather sweeping statement that "a total nuclear ban on both countries (India and Pakistan) should reduce India's vulnerability to terrorism by Pakistan, as its options of conventional retaliation will definitely get enhanced". He could be criticised for taking too simplistic a view of this crucial issue concerning India's security.
