It's possible that Seymour Hersh's latest article amounts to a kind of journalistic pre-emptive attack on the Bush administration's Iran planning. In other words, making public the grave misgivings that Pentagon planners have about the recklessness of a bombing campaign against Iran -- even using tactical nuclear weapons -- might serve to diminish the chance of that happening as the administration gets an earful of editorial outrage. At the same time, the press is treading a fine line as it reports the current "attack Iran" planning. Willingly or not, the media is making itself part of the administration's propaganda campaign intended to make the Iranians believe that the mess in Iraq won't inhibit this administration from military action against Iran. Perhaps the White House really doesn't feel constrained, but it's hard right now to tell whether the media is functioning as a watchdog alerting the public to the administration's wild ambitions or as an attack dog under the administration's command. It seems like a bit of both.I think this is probably the right tack to take on all of the "bomb Iran" speculation in the press.
...As for the likelihood of an attack on Iran, it's tempting to say that the more we hear about it, the less likely it is that its about to happen. At the same time, it's very easy for rational observers to underestimate the Bush administration's capacity for irrational behaviour.
Jim Lobe more or less makes the same point.
