Unless I am mistaken, Benjamin Netanyahu basically wants Congress to trash any deal with Iran because he had a revelatory vision of an alternate universe where Iran gives up everything and asks for nothing in return. Never mind that no one has the faintest idea what could persuade Iran to join a deal that removes every scrap of dual-use material from their borders. Sanctions have long since passed the point of diminishing returns and war is the exclusive domain of John Bolton-level nuts who think they mastered the universe when they learned how to cheat at Risk. Forcing Iran to surrender every scrap of uranium, give itself wedgies and change its name to Nickelbackistan sounds like a fun plan if you’re tabletop gaming with a generous ref, but the real world alternative to Obama’s deal is not a nuke-free Iran. The only real alternative is the previous status quo plus ratcheting tensions that push Iranian hard-liners inexorably towards a nuclear arsenal. The more war looks like the west’s single and only plan the more Iran will see nukes (correctly) as its only plausible deterrent.
This strategy of spiking a clear improvement for the sake of a perfect yet imaginary alternative, it seems spiteful yet oddly familiar. What was it again? Give me a minute. I am sure it will come to me.
