More terrorists are about to die

That's very subjective and depends on too many variables. For pacifists, traitors, & surrender monkeys it was too expensive as soon as it began. They downgrade the threat Iran poses, despite 47 years of history, and are not concerned about the possibility of them getting nukes (or don't care). For those who see how dangerous Iran really is and recognize that they can never be allowed to have nukes.
Because of their fanatical ideology, we can be reasonably certain that they would use them if they had them, targeting the US ("Great Satan"), Israel ("Small Satan"), and others in their megalomaniacal fantasies of a new caliphate. It sounds crazy because it is. Fanatics don't think the same way as the rest of us and don't care about nuances.
There are lots of variations in between.
