Maybe we should blame the West.
Our strategic horizon, in the times of the great maharaja Ranjit Singh, was limited to Northern India, Afghanistan and maybe Tibet (which one of Ranjit Singh's generals offered to conquer after he conquered Ladakh). But starting in 1953, our "brightest officers" were sent to study at American institutions of strategic learning. They came back with half-baked theories which they proceeded to teach in their own "National Defence University". From such seeds grew poisonous fruits like "strategic depth" and Shireen Mazari. The rest is history.
Islamofascism and Islamist extreme and murderous factionalism (exemplified by the Kharijites and now the TTP) have always been present (actually or potentially) in the Islamicate world and were available for use, but without the generous assistance of the University of Nebraska, would we have reached such brilliant heights?
Now, the genie is out of the bottle. And our Rommels and Guderians have no clue what to do, and more important, no vocabulary with which to construct an alternative. I think (and hope) that the pressure of economic necessity will give birth to alternatives at some point. Until then, we are condemned to more of the same.
The only rays of hope are that Indian "strategic thinkers" like B Raman seem to have more sense than Shireen Mazari and may actually help rather than hinder the transition. And the Chinese pulitburo (though not necessarily the PLA) is reasonably sane. On such thin threads hangs our fate....
