It was very clear that Pakistan Army was supporting drone operations long before Wikileaks - there are friggin satellite pictures of US drones on Pakistani airbases.
I have to wonder why there is a contention now though over if they want them there or not? Seems that making it all clear and documented would be very simple.
Perhaps they changed their mind and no longer wish them to act there? I want to read more into the issue, but all I can think is that if they withdraw their consent, then we should leave immediately.
