What does the Iranian government and the newly appointed Iraqi government have in common?

Does anyone find it odd that terrorists are supposed to be coming from Iran, a majority shiite country to fight an elected shiite government in Iraq?

So we fought the Sunnis who were fighting the shiites and are now fighting the Iranian Shiites who fought against the Sunnis?

I think I'm confused.

Actually, we were fighting various factions all along.

For example, in 2004 we defeated Al Sadr's militia (an Iranian proxy army) in the battle of Karballa. In that same year we defeated the Bathist radicals in the Battle of Falluja, and the Sunni radicals in the battle of Samarra.

And the Iranians are desperate to keep a true democracy from forming and taking root in Iraq. They are (rightfully) afraid that thier own people will begin agitating for the same freedoms the Iraqi people now have.

In addition, Iran is having an issue with declining oil production. As a result, they are looking at the oil fields in Southren Iraq and those in Kuwait as potential revenue sources if they can get their hands on them.

About this time last year the Iranians tried to grab Basra with their proxy army. Instead the new Iraqi army proved their mettle by defeating these militias virtually singlehandedly.
