The authors describe possible regional security structures and bilateral U.S. relationships with Iraq and Afghanistan. They recommend that the United States offer a wide range of security cooperation activities to compatible future governments in Kabul and Baghdad and should also plan to hedge against less-favorable contingencies. They emphasize that the U.S. Air Force should expect to remain heavily tasked for the foreseeable future.This book frames potential long-term U.S. security relationships with Iraq and Afghanistan in a regional context and posits roles of U.S. forces, especially the Air Force, in supporting these relationships under a variety of contingencies.
