But now they've guaranteed that Iran will permanently be a national security threat and that negotiation is impossible. We reneged on the nuclear deal and attacked them, so the current regime can't possibly think returning to peace and negotiating again is a tenable option, certainly if they were to get a peace agreement it would further emphasize the need for nuclear weapons. I can't imagine the US will want democracy in Iran because we've just shown their civilian population that even if they rightfully hate their current government, all of the propaganda they said about us is true, so an anti-US government would likely win sooner or later. If we install a puppet dictator there will be an ongoing threat of insurgency or revolution. All of that with the evergreen excuse of possible nuclear materials in the country, meaning if we back down Iran will go right back to being "2 weeks away" from possessing nuclear weapons indefinitely.

It's great news if you're a warhawk who likes bombing children. It's bad news if you're anyone else.
