The United States and its allies must be ready to deter a two-front war and nuclear attacks in East Asia
By Markus Garlauskas
Introduction
“If hostilities were to renew on the [Korean Peninsula] it is not a matter of ‘if’ the Chinese Communist Party will intervene, it is when … This has been a very difficult topic for us to address as an alliance.”— Retired Gen. Robert Abrams, former commander of US Forces Korea (USFK)1
“I’ve wargamed conflicts with China and with North Korea dozens of times. If we look at a map and consider the forces involved, it is almost impossible for either to occur without some form of simultaneity.”—US defense official, name withheld
“If the political survival of Xi Jinping or Kim Jong Un is at stake in [a] military conflict they are losing, escalating to a limited nuclear strike would be rational … hesitating to use nuclear weapons would be the irrational act.”—US intelligence official, name withheld
The challenges to deterrence in East Asia have begun to change fundamentally in recent years, putting them on track to present grave risks to US national security interests over the coming decade. This report summarizes the results of a study focused on two of these emerging and interrelated challenges to deterrence in East Asia. The first is the potential for a conflict with either the People’s Republic of China (PRC) or North Korea to escalate horizontally and become a simultaneous conflict with both. The other is the possibility that either or both adversaries would choose to escalate vertically to a limited nuclear attack—rather than concede defeat—in a major conflict.
