Excellent piece by a veteran Intelligence officer but may I add that any infilteration has to be countered. Spying 'business' has been in operation for centuries - right from the days of legendry CHANAKYA. Point to be kept in mind is for the Indian agencies to keep a tab, track and utmost vigilance be it the Armed forces, Para Military outfits, or for that matter for RAW and I.B. There have been numerous cases of defections amongst indian officials including at time srnior level officers. TV Kumar
