The US is set to present a dossier detailing Iranian influence over shi'ite groups in Iraq. But apart from the basic hypocrisy here - does a government which invaded and occupies a country to support its "national interest" really have any basis to complain when people use similar tactics against it? - this also reeks of the selective release of "evidence" that preceeded the Iraq war. There's the same reliance on exiles for "intelligence", and of course the same purpose: to whip up public support for war. All it needs is a "B-team" within the Pentagon to be shaping the evidence around the policy, and the sense of history repeating itself will be complete.
Marx famously said that history does repeat - the first time as tragedy, the second time as farce. It looks like we are about to have the latter on our hands, unless we stand up and say "no".
