Sound analysis.WASHINGTON - For many months, the administration of US George W Bush has been complaining that Iranian meddling in Iraq is a threat to the country's stability and to US troops. The irony of this publicity campaign over Tehran's alleged bid to undermine the occupation is that Iran may well be the main factor holding up a showdown between militant Shi'ites and US forces.
The underlying reality in Iraq, which the Bush administration does not appear to grasp fully, is that the United States is now dependent on the sufferance of Iran and its Iraqi Shi'ite political-military allies to continue the occupation.

Since then, US officials have avoided giving any estimate of the Mehdi Army's strength. But according to a report published last month by London's Chatham House, which undoubtedly reflected the views of British intelligence in Iraq,
the Mehdi Army may now be "several hundred thousand strong". Even if that estimate vastly overstates his troop strength, it reflects the sense that Muqtada has the strongest political-military force in the country - because of the loyalty that so many Shi'ites have to him.

If Muqtada and his followers are already preparing for a showdown with the US occupation forces,
the only factor that appears to be restraining the Mehdi Army now is Iran. After all, Tehran's interest lies not in forcing an immediate withdrawal of US forces, but in keeping them in Iraq as virtual hostages. The potential threat to US forces in Iraq in retaliation for an attack on Iran is probably Tehran's most effective deterrent to such an attack. Asia Times
