To be fair to Pakistan, US is pushing the GoP into a corner. 2011 was one of the most challenging times for any government in Pakistan trying to keep an even keel on the relationship with US.
Raymond Davis, OBL, Mehran, Salala, open rehtoric by low and mid ranking military and civillian officals, and the pressure on Haqqani Netwrok, stopping or scalling down of aid and on and off reviews of the relationship.
Delay in supply of essential equipment etc. also did not help the Pak military high command infront of their own constituency. This kind of pressure was bound to eventually lead to some sort of readjustment in the relationship.
US Cogress every year reasses the relationship with Pakistan and in the process, some times embarrases it's own Government! Some times this process takes up to a year specially when agreeing to new packages.
It is time that we, given the multifacated dynamics of our relationship with US, specially given the withdrawl from Afghanistan and the upcomming elections, reveiw threadbare, the pros and cons of this relationship and the price and pressure points for continuing what we were doing before.
If it take six months to review it -- let it be six months -- if it takes more time than so be it. If we can wait endlessly for the promised funds/disbursments for money already spent than maybe it is time that the US also show some patience.
I for one think that OBL, Sallala incident were badly handled by US. If it was counter productive to lay blame on in theater commanders in Afghanistan because it will lower the morale of their troops than the same is true on this side of the border as well. The deciding factor should have been -- who has more to loose? It seems US saw the equation differently. Now it is time to pay for, in my opinion, a wrong decsion. The cost will be atleast six times more, if not higher to move goods overland through other routes.
Right now it is a game of patiance and what can be extracted on the plus side from both perspectives.
