Taking a leaf out of Teresita Schaffer's piskolgical observations (which go a step beyond my own pisk-obs in my ebook) we can perhaps model Pakis reactions to the US as a spat between two previously friendly
biradaris.
One biradari has seriously screwed the echandee of the other.
If weaker biradari screws echandee of stronger biradari - stronger will beat/kill weaker
If both are equal - there will be a fight - or at least animosity
But if the biradari that insults the other is extremely powerful, the maintenance of honor requires that the weaker one (Pakistan) makes a big hue and cry and demand something to restore honor (It won't be money) but should not get into a confrontation. That will add to further loss of honor - which means civil war/coup in Pakistan.
The US has to make some gesture that will make the US appear to genuflect before Pakistan. The only other alternative is to get a middleman ( which is what the Pakis always attempted while negotiating with a weaker India). Teh Saudis may be able to help here - by saying that they will step in and pay Pakistan money while Pakistan gains echandee by "refusing" US ad. US aid will come via Saudi with a wink for the US and a statement of "
Bahut sorry ho gaya"
