Laura Rozen has been hosting a roundtable at Mother Jones (parts 1, 2) on the likelihood of an imminent U.S./Israel attack on Iran. It comes on the heels of another article by Sy Hersh in the New Yorker asserting Congress and the President have negotiated funding for continued covert action inside Iran. While I don't want to dismiss Hersh's long and praiseworthy career in journalism, he has been beating a similar drum for a couple of years now with no proven action yet. And most of Rozen's expert panel seems to agree with my skepticism. That said, perhaps it's always best to err on the side of caution.
Also, via Juan Cole, no less than Adm. Michael Mullen, chairman of the joint chiefs of staff, has warned about the potential consequences of a military strike on Iran.
