Barfly anna_missed points to a snippet from Juan Cole:
Sadr spokesman Salah al-Obeidi (al-Ubaydi) in Najaf bitterly attacked Iran,
accusing it of seeking to share with the US in influence over Iraq. He
pointed to the Iranian’s regime’s failure to condemn the long-term
mutual security agreement being crafted by the Bush administration and
the al-Maliki government.
and muses:
With the Sunni resistance temporarily co-opted, the Sadrists branded as "special groups" beholden to Iran, and being the last remaining large group resistance to occupation (& likely to win a major victory in elections), along with the inexplicable abandonment (by Iran) of Sadr – there is reason to believe Iran and the U.S. may have reached some kind of back channel endgame collusion. This of course – because of the non-stop anti-Iranian propaganda currently being employed – is the last thing anybody would expect. Which is a near perfect context, should it actually be true.
Possible? Yes.
Likely? Hmm …
