Iraqi Shiites Copying From Their Hezbollah Cousins in Lebanon?

Counterterrorism Blog -- It shouldn't surprise us if we find that the Shiite militias have prepared for the same type of warfare engaged in by their Hezbollah cousins in 2006, using Iranian arms, IRGC advisers and trainers, and similar tactics.
The obvious difference between Lebanon 2006 and Iraq 2008 is the direct action in Iraq by the U.S. military, who are now far more efficient in counterinsurgency and urban warfare than the Israelis were entering the 2006 conflict. Did the Shiite militia desire such a reaction? Is that why they shelled the Green Zone so early in the conflict with the Iraqi army, to draw the Americans in and inject more uncertainty over Iraq into the 2008 election cycle?
Shiite militia leaders have already achieved one strategic goal: they showed Pentagon planners and American voters that the Iraqi army is nowhere ready to secure Iraq, much as Hezbollah exposed the weaknesses in Israeli armed forces. We can also expect that unless the American military completely wipes out the Shiite militia (an unlikely outcome given the tactics of the militia), the Shiites will take another page from Hezbollah leaders and claim victory, thus raising the morale of their followers and their reputation on "the Arab street." And that would mean another strategic victory for their Iranian backers.
