In the midst of the COVID-19 crisis, the prime minister of Australia, Scott Morrison, launched a new defense and security strategy for Australia. This strategy reset puts Australia on the path of enhanced defense capabilities. The change represents a serious shift in its policies towards China, and in reworking alliance relationships going forward. Joint by Design is a book about Australia, but it is about the significant shift facing the liberal democracies in meeting the challenge of dealing with the 21st century authoritarian powers. The strategic shift from land wars to full spectrum crisis management requires liberal democracies to have forces lethal enough, survivable enough, and agile enough to support full spectrum crisis management. The book provides an overview of the evolution of Australian defence modernization over the past seven years, and the strategic shift underway.
