We are all screwed if Iran gets a nuke. And we may be just as screwed if the United States attacks Iran to keep Tehran from getting that nuke.
Okay, I'm paraphrasing a bit. But that's the core of the message from America's top military officer, who reiterated his canyon-deep reservations about any military solution to the Iranian nuclear crisis. Sure, such strikes might set back Tehran's atomic weapons program -- for a while. But the "unintended consequences" of a hit on Iran's nuclear facilities could easily outweigh the benefits of that delay, Joint Chiefs of Staff Chairman Admiral Mike Mullen told a forum at Columbia University.
