ABSTRACT
This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book addresses a related, yet more controversial, argument that states are able to unilaterally enforce what can be viewed as the collective will, either that which is contained in resolutions of the UNSC. It provides a comprehensive reaffirmation of the robustness of international law governing the use of force to superpower manipulation. The book focuses on the doctrine of expanded self-defence that has been championed by the Bush administration. It aims to discern the approach to the jus ad bellum that appears to have been initially adopted by the Obama administration. The George W. Bush administration also attempted to expand the permissible norms of behaviour so as to incorporate the possibility of taking pre-emptive forcible defensive measures. In particular, under the administration of former President Bush international efforts to combat climate change through international law.
