Is this out of spite?
The successful snatch and killing of Osama bin Laden, the self-acclaimed mastermind of the twin tower bombing by two commandered commercial planes without advance warning to the Pakistani intelligence community may have made some people inside Pakistan orchestrate a disclosure of the CIA station chief in Pakistan. Pakistan though it is harboring KNOWN terrorists without its blessing is a recipient of billions of dollars of military aid from the U.S.This is what the U.S. gets in return for the successful elimination of bin Laden.
The best course of action against this Islamist state is for the U.S. to shift favor to India which suffered a terrorist bombing in Mumbai (Bombay of old) in the recent past. What's irritating is that Pakistan is ignoring appeals of Indian leaders to bring to justice the perpetrators of this cowardly dastardly deed, who are known to hide in Pakistan. In an unbiased view, India is more tolerant of religions (there are Muslims in Indian aspects of life) compared to absence of HInduism in Pakistan. Moreover, India suffered much from Islamic terrorism. The U.S. and India should be closer and not treat Pakistan as favored partner.
Of course due to vagaries of politics, the U.S. is finding it expedient to support Pakistan to help in reigning extreme elements in Afghanistan. But if Pakistan as a country behaves as if it is in cahoots with the extremists(Pakistan suffers too from extremists), there is no cure but for the U.S. to decrease aid spending for Pakistan.
