The congressional hearings into the Iran nuclear deal continue apace. Steve Benen points us today to this lovely exchange between Sen. Lindsey Graham and Defense Secretary Ashton Carter:

Graham: Does the Supreme Leader’s religious views compel him over time to destroy Israel and attack America? Carter: I don’t know. I don’t know the man. I only — Graham: Well let me tell you, I do. I know the man. I know what he wants. And if you don’t know that, this is not a good deal. Graham: Could we win a war with Iran? Who wins the war between us and Iran? Who wins? Do you have any doubt who wins? Carter: No. The United States. Graham: We. Win.

So there you have it: (a) the Ayatollah unquestionably wants to destroy Israel and attack America, and (b) there is no doubt America would win this war. This sounds like mighty poor strategic thinking on the Ayatollah’s part to me, since presumably he knows as much as Lindsey Graham about the relative military strength of Iran and the United States. But I guess his pesky religious views compel him to commit national suicide anyway.

Now, you might be skeptical that Graham knows the Ayatollah as well as he thinks he does, or knows his religious views in any depth either. But even if we give him the benefit of the doubt on that score, his apparent view of things still doesn’t make sense. If the Ayatollah is as committed to war as Graham thinks, why would he bother with this deal in the first place? According to conservatives (I’m not sure what the CIA thinks these days), Iran is currently less than a year from being able to build a nuclear bomb. So why not just build a few and start the war? It can’t be because the sanctions matter. If war is inevitable thanks to the Ayatollah’s religious views, but America is going to win the war by reducing Iran to a glassy plain, who cares about a few more years of sanctions? Most Iranians are going to be dead a few hours after the war starts anyway.

So….it’s all still mysterious. Conservatives don’t like the deal Obama negotiated. Fine. But we can’t go back to the status quo. If we pull out of the deal, economic sanctions will decay pretty quickly and Iran will have lots of additional money and be a year away from building a bomb. The only other alternative is war. Graham is more open about this than most conservatives, but even he realizes he has to be cagey about it. He can’t quite come out and just say that we should go to war with Iran before they build a bomb. So instead he tosses in an oddly pointless question about who would win a war between Iran and America. Why? Some kind of dog whistle, I guess. Those with ears to hear understand what it means: Graham wants to see cruise missiles flying. The rest of us are left scratching our chins.

It all just gets weirder and weirder. The deal on the table, imperfect as it might be, doesn’t restrict American freedom of action at all. Plus it has a pretty stringent inspection regime and would prevent Iran from building a bomb for at least ten years—probably longer. That’s better than what we have now, so why not go ahead and sign the deal and then use the next ten years to figure out what to do next? What’s the downside?

I can’t really think of one except that it makes a shooting war less likely over the next decade. I call that a feature. I guess Graham and his crowd call it a bug.
