After a decade spent emphasising counter-insurgency and counter-terrorism operations, finding a credible response to China’s anti-access/area-denial capabilities is now the central task confronting US military planners.

Beyond Air-Sea BattleChina’s military build-up, particularly the expansion of its long-range nuclear forces and its development of ‘anti-access/area-denial’ (A2/AD) capabilities, poses a serious threat to both the American position in East Asia, and the security of other regional powers. The growth of these forces challenges Washington’s ability, and perhaps its willingness, to project power into the region. This could call American security guarantees into question, eventually undermining the United States’ place as the dominant Asia-Pacific power. Left unchecked, perceived shifts in the regional military balance away from the US and its allies towards China could also raise the risks of miscalculation and deterrence failure. 

After a decade spent emphasising counter-insurgency and counter-terrorism operations, finding a credible response to China’s A2/AD capabilities is now the central task confronting US military planners. This Adelphi analyses the debate over the future of US military strategy in Asia. It identifies and assesses three approaches to the problem; highlights their likely implications for weapons procurement, force posture and alliance cohesion; and outlines a potential synthesis combining elements of each.

'Friedberg’s fair, balanced dissection of the arguments both for and against Air–Sea Battle, as well as the alternative approaches offered by critics, should be the starting point for any future debate about US strategy in the western Pacific. No one has done a better job of outlining the debate over the concepts underpinning the Air–Sea Battle approach.'
Eric Edelman, former US Under Secretary of Defense for Policy, 2005–09

'Aaron Friedberg’s Adelphi successfully frames one of the most important national-security questions the United States is now facing: how can we sustain a balance of military power that deters coercion and reassures our allies in the face of a stronger and more confident China? Friedberg correctly warns that this challenge will be no small task, requiring careful military investments, alliance coordination, and a new commitment to assessing Chinese decision-making.' 
Congressman J. Randy Forbes, US House of Representatives

'An American strategy for China requires analysis that is informed by a deep understanding of history and a sober but courageous review of the choices facing the United States. Friedberg provides both in this timely monograph.'

  • Introduction

    In Asia, as elsewhere in the world, the strategic position of the United States rests ultimately on its ability to project power over great distances. This unique capacity enables the US to extend security guarantees to its allies, who in turn provide it with local bases and facilities. Despite ongoing improvements in the technologies of communication and transportation, these remain essential to the task of sustaining US forces thousands of...
  • Chapter One: An emerging challenge

    The Chinese military capabilities that today represent an increasing threat to the US position in East Asia are themselves a response to a danger that People’s Liberation Army (PLA) planners first began to perceive as emanating from the United States over two decades ago. In fact, the chain of causality can be traced even further back. The high-tech weapons and concepts of operation that caused Chinese analysts such anxiety in...
  • Chapter Two: A belated response

    The forces and doctrine described in the previous chapter present American strategists with four distinct but interrelated challenges. Firstly, the People’s Liberation Army’s (PLA) expanding anti-access/area-denial (A2/AD) capabilities will make it far more difficult and dangerous for the United States to intervene in a conflict on behalf of its regional friends and allies, and could conceivably deter it from doing so. As recently as the late 1990s, an American president...
  • Chapter Three: The direct approach: Air–Sea Battle

    There are, at present, two broad schools of thought regarding the future of American military strategy in Asia. On one side are the advocates of what might be called the direct approach. Analysts and officials in this camp argue that, in the event of hostilities, the United States would have no choice but to defeat and disable China’s anti-access/area-denial (A2/AD) capabilities using a variety of offensive and defensive means, including...
  • Chapter Four: Indirect alternatives

    Largely in response to ASB’s perceived dangers and inadequacies, a number of analysts have proposed that the US and its allies instead adopt some kind of indirect response to China’s growing military power. While several alternatives have been advanced, all eschew direct attacks on Chinese territory, instead primarily depending on the application of American and allied naval power to bring Beijing to terms. Indirect strategies can be subdivided into two...
  • Conclusion

    Whatever its eventual dimensions, the American response to China’s anti-access/area-denial (A2/AD) challenge will involve a blend of direct and indirect approaches. The United States will likely enhance its capabilities for striking at least some targets on China’s mainland, while also strengthening its capacity to wage war in the waters off China’s coast. Because US planners must pursue an array of objectives, including deterrence, reassurance, preparations for war and the conduct...
