If this is the case, then Pakistan must be prepared for a lot of tricks and treats once the withdrawal initiates and eventually concludes. This can be easily learnt from the situation in Iraq after the withdrawal of the US troops was completed. Even though ethnic fissures and sectarian divide devastates Iraq presently, with everyone trying to achieve sovereign control, and a similar fate due to happen to Afghanistan; only this time, the revival of the 1990s scenario will have an added burden on Pakistan in terms of dealing with a hostile and volatile neighbor.
Whatever may or may not happen is what time will tell, but as for the immediate consequences of the eliminat Ha ion of Hakeemullah Mehsud, the situation for Pakistan will be grave for the next one month, and a proper synchronization between the armed forces and the civilian government is absolutely necessary to devise a strategy that can either absorb the coming shocks or act swiftly to end this quagmire.
If at all this situation is left to a political tug of war on the legality or illegality of drones like we always do, Pakistan must prepare to lose a lot in the time to come. Pakistan must understand that where the US is not at all ready to compromise to sacrifice the use of drones to achieve any goals they set (they achieve them or not is an entirely different debate), Pakistan stands to lose much more by this stagnation of demands and also tends to drift away from the ground reality.
Where the declaration of drones strikes is now slowly and gradually becoming a political vote magnet rather than a political strategy and an election rhetoric instead of a state objective, Pakistan must look for alternative options that may either divert the drone warfare back into Afghanistan, create circumstances for the US to cease the use of drones in order to protect their own stakes, and this can be done by making the US economically humble with Pakistan, in a time when the US is also preparing to bear the brunt of an economic lightning storm, due to hit their financial sector by 2014.
