I could see where you might think this argument in favor of an attack on Iran, as advanced by one of the non-Hindrockets at Powerline, came from the bottom of the barrel, but I checked –- and I’m pretty sure this barrel has a false bottom:
There certainly are risks associated with taking such action against Iran, but these risks stem mostly from the fact that Iran has developed (and at times used) the capacity to cause much harm in the region. Thus, citing these risks tends to underscore how much we have to fear from allowing Iran to gain the additional capacity to cause harm that nuclear status would confer.
Let that sink in for a minute, after you’ve read and re-read it a couple of times for clarity. (Don’t waste too much time, though, because you’ll never quite shake that wearing-somebody-else’s-glasses feeling.) Basically, what he’s arguing is that, if we were to attack Iran, they might respond militarily, and their ability to respond militarily justifies our attack — for instance, if we attack Iran with nuclear weapons, that attack is justified by the possibility of Iran’s developing nuclear weapons, which could then create a nuclear-weapons crisis in the Mideast.
Or, to reduce the scale from geopolitical to interpersonal, let’s say you’re at a bar, drinking a whole bunch of beer and about eight or nine shots of tequila, and you lean over and tell your buddy: “I should go punch that guy over there. Yeah, that guy with the mustache, shooting pool. He thinks he’s so bad, he thinks he’s so tough, just because he’s got a mustache and he’s punched other people before. But if I punched him, he’d probably punch me back. And hard, too. Thus, the risk that he might punch me back only serves to underscore how much I need to punch him right now, before any trouble starts.â€?

At which point, your logic has become so circular that you and your buddy both get the spins something awful, you barf on each other, no one punches anyone and you stagger out of the bar, arms around one another, alternately cursing and hiccuping. (Results may vary as scale increases.)
But whatever the scale, it’s when people in that state operate vehicles, surgical instruments, heavy machinery or deadly weapons that tragedies can occur.
