What is not so obvious are the consequences flowing from two major aspects of Iran's activities and policies
The joint attacks on Iran successfully eliminated most of the high level leadership of the Islamic regime, as well as many of the Iran Republican Guards, and numerous military supply, support, and naval facilities. The Iranian people have been called to take back their country, and the response from expatriate Iranians has been overwhelmingly positive.
All this and more was anticipated and reasonably expected. The attacks on other middle-Eastern countries might have been a bit of a surprise, but not a huge one as Iran has seen many of them to be collaborators with the US and Israel, notably through the Abraham Accords. What is not so obvious are the consequences flowing from two major aspects of Iran's activities and policies.
Iran has been a major sponsor of global terrorism, and especially destabilizing in the middle-East. The regime had sworn to eradicate Israel, and sponsored many terrorist groups, providing training, weapons, and other support in their attacks on Israel. Their efforts to develop nuclear weapons, coupled with development of long range ballistic missiles, posed a threat not only to Israel, but to most of Europe and our US allies. Without a hostile theocratic Iran, support for terrorism would be largely cut off, and the nuclear threat to Western countries eliminated. In addition, the rise of a secular democratic Western aligned state in Iran, similar to what existed before the Islamic takeover would go far toward eliminating a source of conflict in the middle-East.
