It appears that attacks by Iranian backed militia on U.S. forces in Iraq are decreasing. A combination of diplomatic engagement and military operations get the credit. It was just a few weeks ago that Defense Secretary Leon Panetta warned if the attacks didn’t stop, the U.S. would take some action. Joint Chiefs Chairman Admiral Mike Mullen who stopped into Iraq on an unannounced visit said he still in a wait and see mode as to where the trend can be continued. 14 U.S. service members were killed in hostile action in June.
