US extended nuclear deterrence in Europe and East Asia: a comparative analysis

In: Asian affairs, Band 53, Heft 3, S. 500-519

Abstract

Analysing the alliance system in Europe and Asia in a comparative perspective also demands having a look at the specific role of nuclear weapons in the defence doctrines, and more in particular the role of US extended nuclear deterrence. The main question that this article wants to resolve is: what are the similarities and differences in both regions with respect to extended nuclear deterrence? This (comparative) descriptive analysis is complimented with the following predictive question: which trends in both regions make it likely that extended nuclear deterrence will be strengthened, weakened, or maybe completely disappear? To answer these questions, the following structure is followed: first, the concept of extended nuclear deterrence will be described; next, this concept of extended nuclear deterrence will be applied to Europe and Asia; lastly, three trends that have an impact on the current debate on extended nuclear deterrence are analysed: 1) the deteriorating security situation; 2) the changing balance of power, and more in particular the relative decline of the US and the rise of China; and 3) the evolving nuclear arms control and disarmament regime, including the arrival of the Treaty on the Prohibition of Nuclear Weapons (TPNW).
