Details
Joint Doctrine Note (JDN) 1/19, Deterrence: The Defence Contribution, outlines how Defence contributes to deterrence activities carried out by the UK government. It reflects the return to prominence of deterrence in national and international thinking.
This JDN seeks to explain how deterrence works in the 21st Century context, as opposed to that of the bipolar Cold War. It explains the context for deterrence activity, against which Defence contributes to national security and deterrence as part of an integrated and cross-government approach. It covers a significant number of deterrence factors and considerations and seeks to explain their complex interrelationships.
Who should read this publication
JDN 1/19 informs a broad civil and military readership. It provides guidance to those in Defence responsible for planning, developing, deploying, and commanding and controlling deterrence activity or those who aim to create deterrent effects within other operations.
It also aims to provide other government departments with a broad understanding of Defence’s contribution to deterrence as part of a fused, integrated/multi-agency approach to deterrence.
Note: JDNs are developed to fill doctrinal gaps or to stimulate discussion for informing future doctrine. They are authoritative, based on current practice and established doctrine, but they are not ratified.
