If army was not involved in politics & if it was doing its constitutional duty assigned to it in the constitution it wouldn't blame for anything either. The fact of the matter is ISI and jihadis in army are playing double game & it would not surprise me if someone within ISI was involved in this.
So Now when Army has totally out of the picture, they are still being blamed!! funny isn't it. The Politicians are however, so weak that they are not been able to appoint a single person in the huge cabinet for Interior Affairs and have to rely on IQ of Rehman Malik to sort things out. what a pitty!!!
I agree the Musharaf is responsible for the mess we are in and army was backing him then, but we should not forget that it is again army who had withdrawn their support for mushy, which have ultimately resulted in his resignation, and if Zardari and other politicians had guts, they could have easily have hold him in the court of law for his mis-doing...but unfortunately this is not the case, the leadership has its very own interest, these interests are seem not to be in the favour of Pakistan.
To me Politicians are equally responsible for Army's involvement in the affairs.. it is their very own weakness of character which has enabled them to fill the vaccum.
BTW, why do u think RAW or CIA or anyother Agency is not behind the attack? Did RAW changed their mission and now working in the interests of Pakistan???
