IIRC, it was supposed to put Iran's nuclear program behind by several years, but because it escaped into the wild---and thus endured far greater public scrutiny than it would have otherwise---the Iranians found out about it much earlier than they were intended to, so it didn't have quite the impact that the US/Israel were hoping for.
