Kargi lis no different than India's aggression in Saichen, and Kargil is disputed territory. The possible reason for using 'Mujahideen' was to avoid escalation. I think the GoP should have used India's aggression in Siachen to justify the Kargil incursion globally. The world would have little room to complain had the GoP said, fine, we'll withdraw from Kargil when the Indians wthdraw from Siachen.
And as for the PM not knowing, the jury is out on that - officials familiar with the events, including a Musharraf critic, Kayani, indicated that Nawaz was completely aware of the operation.
Finally, India has to her great credit things like supporting the Pashtun, Baluch and East Pakistan insurgencies, and supporting terrorists in at least two of them, along with supporting the LTTE, so lets not get self righteous with the 'million acts of terrorism' canard.
Should I believe a SUPER MODERATOR of PDF that Nawaz was aware of Kargil, while the whole world knows he was not? I don't think so, or........errrr! maybe I will if you can prove that you are General Kayani or Shuja Pasha.
Also, India does not support Pashtun and Baluch rebels. East Pakistan happened long back, and Bangladesh is still indebted to us for that (I hope so, unless "being grateful" is a dead term). As about supporting LTTE, we helped Sri Lanka covertly, to destroy it. I hope you read international news.
Lastly, Kargil and Siachen is Indian territory, and we have proved that to Pakistan, I believe.
