20 January 2010: When this writer wrote two pieces earlier this month seeking a new NSA ("A new NSA?" 4 January 2010 and "Terrorism & bunglers," 8 January 2010), he had little idea that the issue was in the works, since it would be presumptuous to assume that the above-cited commentaries played any role in M.K.Narayanan's present exit from that post. But there was also a call in those writings to review the functions and tasks of the national security advisor, and media reports suggest that such a review is underway, although the prime minister, Manmohan Singh, apparently does not wish immediately to rearrange the existing architecture.
