I've written before that there is a very real threat that the Bush administration could go for double or nothing and launch a major military campaign against Iran in the next 18 months. But I had largely discounted this weekend's rush of rumor and sketchy details about the possibility of an imminent attack. Among other reasons, I have a well-grounded skepticism about stories about US politics I read fully-formed and attributed in the British press before any American publications seems to have caught wind of it. But maybe I've dismissed this too quickly. Todd Gitlin and George Packer have more.
