i'm surprised that the SCO is letting them attend. i thought the whole point of the shanghai cooperation organization was to create an international security group that didn't have the world's lone superpower as a member (which inevitably leads to american domination)
maybe with a more multi-laterally inclined president they're not as prickly about the american presence. or maybe this is just an elaborate set-up, like a blind date. the SCO members think if they just can get the u.s. and iran alone together in a room, something like love will blossom.
