I think it is high time we conclude that our intelligence agencies performance have been dismal . I dont see any downside of seeking assistance of the best reputed agencies like CIA , Mossad , MI5 or KGB .
People seem to just overreact and emotional over US involvement . We should not forget that during the last 4 years after Sept 11 ,2001 the CIA has managed to compile a huge database on suspcicous people . The CIA could also act as a source to locate people in Pakistan etc .. The Govt of pakistan would never help us directly because of obvious reasons but might as well do so through CIA .
Of course , we should keep in mind our autonomy etc but operational help like accessing the database should be taken . Similar to miltary hearddware and technology , the Mossad is known to have the best and well trained agents . It might be a good idea to seek assitance in training and managerial expertise .
The British MI5 has a huge array of devices , famous from James Bond era ..:).
