Take it easy! Sensible readers take the unverifyiable claims not with a pinch but with a handful of salt! It might as much be true as much it's not! These kinds of claims happen all over the world such as Gohar Ayub Khan claiming that Field Marshal Manekshaw sold military secrets to Pakistan in 1965 war!
As in the US and elsewhere, I think we too should have a policy that one can reveal the secrets and classified documents after a certain period of time, if we do not have one already! Such a measure would prevent sensation seeking writers from making these kinds of statements.
However, I agree with your concern! There should some restrictions be applied on bureaucrats and also on ministers and other legislators from ever talking on senstive issues that concern national safety! Else, gullible people may believe that it was true much like the canard that was propaged that Nehru was responsible for our losing a part of Kashmir, which is non-sense.
