Debka.com is now reporting Iran's mini-invasion of Iraq, saying:

Early this week, Tehran deployed in southern Iraq and southern Iran contingents of Revolutionary Guards Corps of suicide fighters in anticipation of an American attack on Iranian soil.  Those units were posted to fight off a possible US Marines landing in southern Iran. Tehran believes the American force will be assigned with destroying RG bases and infrastructure in the south and sabotaging the oil wells and installations of Iranian province of Khuzestan.  The RG fighters were dropped by helicopter in southern Iraq on June 24 and 25. Their task will be to launch suicide attacks on US and British bases and command posts in the region the moment Iran comes under American attack.
