In his recent speech outlining the surge plan for Iraq, President Bush stated that Iran was training our enemies and providing "advanced weaponry."
Now the L.A. Times has investigated what evidence there is to support the notion of an aggressive Iranian influence inside Iraq, and have been able to come up with very little.
"The Bush administration has provided scant evidence to support these claims. Nor have reporters traveling with U.S. troops seen extensive signs of Iranian involvement. During a recent sweep through a stronghold of Sunni insurgents here, a single Iranian machine gun turned up among dozens of arms caches U.S. troops uncovered. British officials have similarly accused Iran of meddling in Iraqi affairs, but say they have not found Iranian-made weapons in areas they patrol."
Even in Diyala, the Iraqi province bordering Iran, where one would expect there to be the most obvious indications of Iranian infiltration:
"U.S. troops have found mortars and antitank mines with Iranian markings dated 2006, said U.S. Army Col. David W. Sutherland, who oversees the province. But there has been little sign of more advanced weaponry crossing the border, and no Iranian agents have been found."
