April 2010 the CSBA released the report, "AirSea Battle: A Point-of-Departure Operational Concept," outlining the U.S. military's growing operational difficulties in the Western Pacific Theater of Operations (WPTO). The report argues for the United States to diversify its military strategy away from "the demands of modern irregular warfare" and fielding forces designed for "security threats that are fading into history" to one that highlights the Chinese People's Liberation Army's (PLA) quick ability to field anti-access/area denial (A2/AD) technologies. The authors are quick to point out that they are not suggesting the United States seeks a confrontation or a war with China, but rather "offsetting the PLA's unprovoked and unwarranted military buildup." Michael E. O'Hanlon of the Brookings Institution believes the phrase "AirSea Battle" is politically contentious and should be renamed to "AirSea Operations," which he thinks better reflects the doctrine. "It may seem curious to worry about semantics and political correctness when talking about military systems or plans for war. But in Asia, semantics count a great deal; on a recent trip there, I heard lots of complaints about America's perceived efforts to contain China with frequent reference to…AirSea Battle doctrine." O'Hanlon is a strong supporter of the doctrine but thinks a change in semantics, along with more dialogue and transparency will mitigate the security dilemma between the United States and China. O'Hanlon and James Steinberg argue that "policymakers must put this military doctrine into perspective and not let it become a prescription for unfettered rivalry." The 2014 Exercise Valiant Shield tested Air-Sea concepts. Coordination The Pentagon's new Air-Sea Strategy Office will focus on anti-anti-access/area denial concepts. The House Armed Service Committee has questioned if this office was duplicate of other Pentagon bureaucracy. Kenneth McKenzie defines the United States Marine Corps role in AirSea Battle as an airborne assault force that operates from ships to seize bases. The United States Air Force is responding to the threats against their foreign bases with the Pacific Airpower Resiliency Initiative. In 2014 Seventh Air Force commander Lt Gen Jan-Marc Jouas stated that AirSea Battle would be the new warfighting doctrine for Korea.
