In a country like Afghanistan, where the chief export has for decades been poppies and opium, it should not be at all surprising to find that there are entrenched interests that force a president of that country to walk some fairly tight lines. That’s especially true when the country that put said president into power hasn’t been paying much attention lately. Still, an op-ed by a former State Department official accusing Hamid Karzai of “playing the US like a song” is bound to raise some concerns. . . if not here, than elsewhere in the world where the media pays attention.
