Put me in the "very skeptical but then again I wouldn't be surprised" category:

...there is a strong movement in southern Iraq for the establishment of autonomous Shi'ite provinces as a precursor to introducing vilayet-e-faqih (rule by the clergy) in the whole country...

To head off this threat of a Shi'ite clergy-driven religious movement, the US has, according to Asia Times Online investigations, resolved to arm small militias backed by US troops and entrenched in the population to "nip the evil in the bud".

Asia Times Online has learned that in a highly clandestine operation, the US has procured Pakistan-manufactured weapons, including rifles, rocket-propelled grenade launchers, ammunition, rockets and other light weaponry. Consignments have been loaded in bulk onto US military cargo aircraft at Chaklala airbase in the past few weeks. The aircraft arrived from and departed for Iraq.

The US-armed and supported militias in the south will comprise former members of the Ba'ath Party, which has already split into three factions, only one of which is pro-Saddam Hussein. They would be expected to receive assistance from pro-US interim Prime Minister Iyad Allawi's Iraqi National Accord...
