American military commanders are finding their jobs a lot tougher these days since the U.S. pullout from all of Iraq’s cities and the sudden assertiveness by Iraqi security forces to protect urban areas. Immediately following the June 30 deadline that pushed American soldiers out of cities, the Baghdad Operations Command ordered their American counterparts to cease all joint patrols in the capital, and to limit their resupply convoys to traveling at night only. Iraqi leaders are trying to show their citizens that they are now in charge and that the U.S. is a shrinking factor in security operations. But some American generals are not happy with the way Iraqi commanders are limiting the movements of U.S. soldiers to respond to potential or actual threats from insurgents.
