As I said elsewhere, this is an internal matter. Whether it turns out to have been a coup or not is not the most important question for the political leadership of the rest of the world. The central question is this: Between the leadership of Iran and Israel, whose actions have been defined more by rational self-interest and whose by immaturity and recklessness?
Who would you trust to keep his head in a crisis, Netanyahu or Khamenei?

The Israelis are the wild cards, and anyone in American policy circles who says otherwise should by fired as a liar or a fool.
