- Abstract:
- Although the INF Treaty was originally intended to reverse the deployment of Soviet and US missiles in Europe, its demise may be felt more keenly in the Asia-Pacific where a missile arms race is arguably already under way. The development of new missile technologies has implications for stability as the region’s nuclear-weapons states could see them as threats to the credibility and survivability of their second-strike systems. This could trigger a diversification of missile systems across different platforms or an increase in the number of warheads and launchers to complicate an adversary’s targeting options. The Intermediate-range Nuclear Forces (INF) Treaty ended on 2 August 2019 due to the United States’ withdrawal over long-standing concerns of Russian violations. The agreement between Russia and the US had prohibited the development and deployment of ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometres. Although the implementation of the INF Treaty was originally motivated to reverse the deployment of Soviet and US medium-and intermediate-range ground-launched missiles in Europe, its demise may be felt more keenly in the Asia-Pacific. Despite its primary rationale that Russia’s prolonged violation of the treaty rendered it void, then US president Donald Trump’s administration also cited China as an ancillary reason behind its decision to suspend its treaty obligations. As China was not a party to the INF Treaty, Beijing has been free to make substantial quantitative and qualitative improvements in its medium- and intermediate-range missile arsenal as an important part of its strategy to counter the US and allies’ military power in Asia. Following Washington’s decision to withdraw from the INF Treaty, US policymakers made it clear that they intend to counter China’s growing capabilities by deploying to the region additional missile defences and the previously prohibited classes of ground-launched surface-to-surface systems that now are under development. China’s ballistic-and cruise-missile arsenal, however, is viewed with concern beyond just Washington. Other regional states such as Australia and India also regard the expansion of China’s missile forces with unease, resulting in Canberra and New Delhi developing their own missile systems in response. In the case of the latter this could have downstream effects by causing Pakistan to adjust its own nuclear and conventional missile forces in response, illustrating the potential possibilities and consequences of action/reaction dynamics in Asia spiralling into regional arms-racing. Although the erosion of the arms-control architecture provided in part by the INF Treaty could potentially herald the beginning of more sustained arms-racing in the Asia-Pacific, a regional competition is arguably already under way. The proliferation of conventional and nuclear ballistic missiles in the region is not only apparent in China’s force structure, but also across Northeast Asia, which has had immediate and associated implications in the local and wider region. Developments in North Korea’s nuclear and missile programmes have been especially destabilising, given fears that Pyongyang could threaten the use of nuclear weapons in a conventional conflict were the survival of the Kim Jong-un regime in question. Cumulatively, North Korea’s strengthened missile forces have caused the US and its allies and partners in the region, especially Japan and South Korea, to pursue countermeasures, including strengthening missile defences and developing counterforce capabilities. Doctrines regarding the use of conventional precision attack have also correspondingly shifted, with South Korea embracing the option of using pre-emptive conventional counterforce strikes to deter missile attacks from North Korea. Japan, however, continues to debate how its armed forces might utilise the long-range strike capabilities that Tokyo is pursuing. Some of these developments, especially improved missile-defence capabilities, have resulted in a diplomatic and economic response from China, as Beijing argued that some of these measures undermine its strategic deterrent. China has also warned US allies in the region of possible repercussions if they decide to host US missiles previously proscribed by the INF Treaty. There is therefore the potential that decisions by some regional states to develop their missile capabilities might not only result in immediate action–reaction responses by the instigator’s adversaries, but also wider cumulative consequences undermining the security of multiple states across the region. Against this backdrop, emerging missile technologies carry additional risks and implications for regional stability. As part of a trend that one analyst has described as a ‘missile renaissance’, hypersonic boost-glide vehicle and cruise-missile technologies are being pursued by several states in the Asia-Pacific region, including Australia, China, India, Japan, Russia and the US. The development of these technologies has implications for regional stability since they could be seen as threats to the credibility and survivability of second-strike systems of the region’s nuclear-weapons states, potentially triggering a diversification of nuclear systems across different platforms or an increase in the number of nuclear warheads and launchers to complicate an adversary’s targeting options
