This article uses the example of Russia’s aggressive action against Ukraine as an example of a new form of contemporary war fighting, namely hybrid war, and discusses how Russia has been successful in exploiting vulnerabilities of its opponents. The article reports on the United Kingdom as a case study to discuss potential threats and how these can be countered. While using the United Kingdom as an example, the ramifications of such a hybrid approach also apply to South Africa as a state which is vulnerable in respect to economic warfare, cyberattacks and its energy sector. The suggested counteractions could also be seen as lessons learned for a future South African scenario. It is a further development of a short submission to the Defence Select Committee of the UK House of Commons.
