The militant outfit was based on Pakistani soil, which has now been banned by the Pakistani authorities. However, they were not state (sponsored) actors, unlike Imran Khan who seems to be suggesting that they are. That is called compromising Pakistan's situation internationally. Even the Mumbai probe did not provide any conclusive evidence implicating the ISI/Pakistani authorities in the 26/11 Mumbai attacks, yet Imran Khan seems to think otherwise. There are things that are said in private, behind closed doors, as compared to what Imran Khan did, whether it is well known to everyone or not. Of course the 26/11 Mumbai attacks that were planned partly on Pakistani soil compromised Pakistan internationally, but there are somethings that are said behind closed doors, & other things that are said in public.
I do not want an 'undiplomatic' leader who compromises Pakistan's situation on everything as the PM of Pakistan. Musharraf was by far the better leaders Pakistan has had, he said one thing in public, & another thing behind closed doors. And he never compromised Pakistan's position. Imran Khan also has a lot of his 'facts & information' pertaining to the WOT campaign & other issues wrong. And it is very easy to prove him & his theories wrong.
Not only has he compromised Pakistan's situation in relation to 26/11, he has also compromised Pakistan's situation on Balochistan, Kashmir, the WOT campaign, 1971 & many other issues. The LeT, HuM & other militant groups do not deserve any support, but that does not undermine the legitimate concerns of the Kashmiri people, & Imran Khan has undermined them as well. Of course no militant group should operate from Pakistani soil, but there are somethings that are said behind closed doors, & other things that are said in public. Imran Khan is a simple minded person who does not have the tact or the guile to be a PM.
