Daniel Larison goes there:
Whenever an allied government doesn’t measure up to what the U.S. expects of it, it is tempting to accuse it of perfidy or betrayal, but that avoids considering whether we are expecting something that the ally can reasonably provide. Libya hawks have taken to bashing Germany for its pacifism, which is another way of saying that allies are supposed to act like satrapies: they are not permitted to make independent judgments about policy questions, nor are they allowed to act in their own interests.
Iraq hawks derided Turkey for its opposition to the invasion, and some of them built up entire narratives that portrayed France as our traditional nemesis. Considering how widely loathed our government is in Pakistan, and considering how antagonistic many of our policies are to Pakistani interests, the U.S. has no reason to expect any Pakistani cooperation. For various reasons, we have received some cooperation anyway. Inevitably, that isn’t enough for some people, who seem to expect allied governments to commit a sort of suicide to fulfill our demands.
Goldblog likewise refuses to label Pakistan an enemy.
