Now a bit about Iran's role in the Iraqi insurgency

A dispatch direct from CENTCOM, the U.S. military command center in the region:

Through interrogations of key detainees in the past month, the United States has learned a great deal about Iranian involvement in terrorist activities in Iraq, specifically the financing and training of insurgent groups, the commander of U.S. forces in Iraq said here today.

The interrogation of leaders and members of the Qazali terror network who have been in detention for more than a month revealed that Iran provided the network substantial funding, training on Iranian soil, advanced explosive munitions and technologies as well as arms and ammunition, and in some cases advice and even a degree of direction, Army Gen. David H. Petraeus, commander of Multinational Force Iraq, said in a Pentagon news conference.

Apparently, Iran is supplying some of the more deadly explosive devices, according to the U.S. military (who is on the ground there in contrast to most media outlets). As Centcom reports:

The U.S. has learned more about Iranian involvement in Iraq through the detention of one of the heads of the Sheibani network, which brings explosively formed projectiles into Iraq from Iran, Petraeus said.

This leader’s brother was in Iraq, and was the conduit who received munitions from Iraq and distributed them among the extremist elements.

“Those munitions, as you know, have been particularly lethal against some of our armored vehicles and responsible for some of the casualties, the more tragic casualties, in attacks on our vehicles,” Petraeus said.

The U.S. so far can't determine exactly who in Iran is directing this effort.

Also, there's no evidence that Iran is behind the, in Centcom's phrasing, "the spectacular car bomb attacks in Iraq." So far the military believes these are conducted by foreign jihadists coming in through Syria - along with the pious folk in Al Qaeda.

Here's a question for everybody, especially those readers in the region: So what should the U.S. do about Iran? And what to do about Syria?
