Firstly, K Subrahmanyam is a respected strategic analyst. What he wrote here is largely true. But would like to add few more points:
1. India under UPA made a gigantic mistake by signing Havana Deal, thus equating victims (India) perpetrators (Paki Civic society, ISI, Army, Paki Govt to a large degree). We lost vital internal opinion moulded in favor of India as a victim of viscious Islamic Jehad done by previous 6 years of NDA rule.
