Spencer Ackerman gets it:
It’s emotionally unsatisfying not to proclaim unequivocal support for the protesters. But the truer measure of support, as Trita Parsi told me, is to follow their lead. Moussavi, for instance, has not issued any statement about what he wants the international community to do. If the protesters begin calling for a more direct American response, then that really will have to compel the administration to reconsider its position. But until then, with so many lives at stake, the administration can’t afford to take a stance just because it makes Americans feel just and righteous.
