"As for the civilian gov being on the US payroll, well so is the army"
Not really. The US & the Pakistani Army are in a strategic partnership, not on a payroll.
"they have got a lot of money and it was the Army who let Davis go"
Now who's the conspiracy theorist? First of all, the money was not paid by the American government, but Saudi Arabia. Secondly, it was only after the victims' families accepted the blood money & put their signatures on paper that Davis was released. Thirdly, it was the Pakistani courts that gave the verdict for the release of Davis, not the Army. What's with all the conspiracy theories?
"Zardari cannot change a damn thing"
Zardari can, if he quits being on the US payroll. Imran Khan has already talked about how the civilian government has compromised the nation of Pakistan & the Pakistani people.
