The government could not even prosecute a CIA contractor, I think you know the answer to 'will it order the PA and PAF to shoot down US aircraft.
Protection of airspace is a given, but wikileaks indicate that an unofficial agreement between Pakistan and the US exists on the issued of drone strikes - I believe Zardari was quoted quite explicitly in favor of US operated drone strikes. As such, there is no doubt that the GoP needs to come clean with the Pakistani people and issue a clear command to shoot down the drones if the US does not stop drone strikes in Pakistan, and we can hold Kiyani and Rao Qamar Suleiman (ACM) responsible if those orders are no implemented.
Look - the Army has always derived its power and influence through the support of the people, and typically it has influenced the elected governments to support hawkish foreign and nuclear policies, that have the support of most Pakistanis.
The Army will have no power if it tries to force an elected government to implement policies that Pakistanis find deeply unpopular - Zardari and Nawaz Sharif would probably welcome such an attempt by the Army, since they could run to the media and bash it endlessly, and the Army would be helpless in the face of public pressure and outrage.
There can be little doubt that the PPP at least is supporting drone strikes, and the Army is going along under Kiyani.
Sure, and Gillani seconded him - so lets see Gillani issue an official statement for the US to end drone strikes or have them shot down. I will hold Kiyani and Suleiman responsible then if they refuse to implement the GoP's orders.
If you want proper change, then focus on the correct institution - the government. The Army is not running the show. Pressure the government to comply with the demands of Pakistanis, and then the ball is in the court of the military - will they respect the decision of the civilian government to take on the US or not? Until then there is no justification for criticizing the Army - they are not in power anymore, and we should stop acting like they are and force our elected leadership to be honest and straight with us.
Please see my previous posts on the fact that 'kicking out' does not have any feasible plans for a replacement government.
Do we want a proper democracy where every institution functions as it should or do we want to continue playing these games with ISI/Army subterfuge and lack of transparency in governance? Hold the PPP and PML-N responsible, they are the ones elected to do these jobs. If the ISI/Army does not cooperate, summon them to court and point it out and shame them and remove the leadership of those institutions for not complying with the law
Enough of this 'cloak and dagger' nonsense - lets focus on the fact that Pakistanis elected these people to govern, and they are failing miserably and we need to kick them out and bring in fresh faces. When the Army refuses to listen to the civilian government that Pakistanis elected, we can hurl , abuse and criticism at them as well. But not right now, when the Army is in fact acting constitutionally.
