I've never been a big fan of Hillary Clinton's Foreign Policy. I thought she was a war-monger during the campaign just a couple clicks toward sanity compared to McCain and his "Bomb, bomb, bomb, Iran." I wish that Obama would have found a position for her on the domestic policy side of the cabinet. She is at State to stay, however, and in the wake of the most significant protests in Iran since December of 2009, the US should just keep quiet.
Ever since the election fiasco of June 2009, the current government has been saying that protesters are directed by foreign agents etc. There is a history there (1953) that does not exist for Tunisia or Egypt. The language that Secretary Clinton is now using only reinforces this view, and I'm sure that Iranian opposition leadership do not like it. She's not helping. On some days--I think that's the intent.
