Here is a quote from the L.A. Times:
I agree the symbolism is stark: succeed in getting one spy in and our entire team of advisors can be run off. Our readiness to attribute the actions of a handful of fanatics to the entire Afghan people mirrors the willingness of so many Afghans to attribute the actions of one deranged man to the entire American people. We are allowing terrorist with the support of a small fraction of the population to defeat us. It is a tragedy for Afghanistan and an ominous precedent for our foreign policy and alliances in an age of terror.That said, the violence — in which more Afghans than Americans have been killed — is an ominous reminder of the fragility of the relationship between the United States and its allies on the one hand, and an Afghan populace wearied by a decade of Western occupation on the other. Especially shocking was the execution-style murder of two U.S. service members assigned to the supposedly secure precincts of the Interior Ministry. The gunman, who is still at large, is suspected of being an Afghan police intelligence officer. Afterward, U.S. commanders withdrew Western military advisors from various Afghan ministries as a precaution. The symbolism was stark: Americans couldn't trust their Afghan allies.
