Does shooting at us count?
Well, to be fair, we were flying over their soil.
That's because they are nuclear powers to one degree or another. Confronting them takes on a whole new level of risk once they join that club. That's why it is so important to keep other countries (including Iran) from getting nukes.
Iran is not a nuclear power by any means yet, and just how do you suggest we stop them if they try?
Did Iraq have nukes? Not really. The Israelis took care of that the first time. Do you think that they gave up on it forever?
I don't. And I sure as hell didn't want to be wrong and find out the hard way.
Probably not the dream, but even idiots can dream. And it would have been very difficult, much more than you can probably imagine, for Iraq to restart its nuclear program in any meaningful way.
Eh, that is just me though.
