Jarita, Wikipedia links hardly constitute evidence of a person's actions or affiliations. Given the nature of the source, wiki links are not worth relying on (or need to be highly circumspect) especially something related to secret societies and groups since the page can edited to portray whatever info the editor would like! IKG's action of rolling back covert ops capability is not doubted since many commentators have alluded to it often.
Ramanaji,
I didn't get the 1 in xx odds part of your questions. Assuming that your are asking how much each of the diff areas suffered due to MD/IKG actions, I will give my guesstimate of the efficiencies for each of them with 100% being no negative effect
MD:
1. 100% - No pointers to reduction in these capabilities.
2. 50% - While MD did stop/curtail/expose some of covert assets, not all was lost. So 50-50 is the best guess.
3. 75% - While there are no pointers to reduction/curtailment of these activities, it is safe to assume that the effect of #2 was felt on this part too as some of the covert assets may have been for techint gathering.
4. 100% - No pointers to reduction in the scale or scope of CI ops.
5. 50% - Similar to #2. Could be more but can't speculate until more credible information is available.
IKG:
1. 100% - No pointers to reduction in these capabilities.
2. 75% - Although IKG stopped covert action abilities, I would hazard a guess that it was not directed towards intel gathering abilities.
3. 90% - Based on the above explanation and the fact that technology has improved in the intervening period, I would guess the reliance on covert assets to gather techint would have been reduced, hence lesser impact.
4. 100% - No pointers to reduction in the scale or scope of CI ops. In fact Rattan Sehgal was netted in this period!
5. 25% - Given IKG's wish to improve peace and provide a good will measure, I would hazard that this area was the most hit.
Based on this above exercise, I just had an aha moment. The effect of MD's actions were that we were able to know only 'half' of what we could was happening in Pakistan and we only had 'half' the ability to stop it proactively. The effect of IKG's actions were that we could know 'most' of what we could know in Pakistan but we didn't have 'any' ability to proactively respond. In effect, the Indian response mechanism became mainly reactive with a higher efficiency than from being equally reactive and proactive with a reduced efficiency in MD's time.
As usual I am open to correction.TIA.
