Abandonment, entrapment, and the future of US conventional extended deterrence in East Asia (part I)
In a recent contribution to The Strategist, Rod Lyon argues convincingly that Australia needs to engage its US ally over the future credibility of its nuclear extended deterrence posture in Asia. It doesn’t stop there. Indeed, the current stand-off between China and Japan over the Senkaku/Diaoyu islands is a timely reminder that US conventional extended deterrence also needs refinement, particularly in East Asia.
Traditionally, US conventional deterrence for its East Asian allies has relied on ‘direct defence’, i.e. deterrence by denial through the unmatched ability to defeat any conventional attack against its forward deployed forces and/or allied territory. Up to now that’s been a credible strategy. But today China has embarked on a long-term trajectory to contest US naval supremacy in the ‘first island chain’, which includes Taiwan and parts of the seas surrounding Japan. While the People’s Liberation Army (PLA) still has lots of catching up to do, the gap is slowly closing. Already, American fixed targets (bases) in Japan and South Korea are in striking range of China’s growing missile arsenals. The PLA is also developing systems to pose a threat to high-value moving targets (US carrier strike groups). The aim is to make it too costly for the United States to intervene in a future regional crisis between China and its neighbours.
This development has important ramifications for the American deterrent posture. Read more
